[0001] TOOL FOR NUTS, BOLTS, AND PIPING

[0002] RELATED APPLICATIONS

[0003] This application claims the benefit of priority under 35 USC §119(e) of U.S. Provisional Patent Application No. 63 / 739,739 filed on 30 December 2024, the contents of which are incorporated herein by reference in their entirety.

[0004] FIELD AND BACKGROUND OF THE INVENTION

[0005] The current invention, in some embodiments thereof, relates to a tool for tightening and loosening nuts and bolts, and / or removing and / or attaching piping, particularly, but not exclusively, to a compression fitting.

[0006] A wrench or spanner is a tool used to provide grip and mechanical advantage in applying torque to turn objects — usually rotary fittings, such as swivel joints, swivel fittings, rotary unions, rotary connectors, nuts and / or bolt heads — or keep them from turning. The most common shapes are called open-end wrenches and box-end wrenches. There are a plethora of wrenches of varying sizes, shapes, and designs. Some of the adjustable wrenches include the adjustable wrench, the self-adjusting wrench, the monkey wrench, and the pipe wrench.

[0007] With compression fittings for water or gas tubes, there are various mechanisms and techniques for inserting the tube into the compression fitting. Most commonly, brute force is used, often stripping or compressing the fitting. Removing a tube from a compression fitting is very difficult. When brute force fails, many practitioners simply cut the tubing below the fitting and discard the compression fitting.

[0022] DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION

[0023] The current invention, in some embodiments thereof, relates to a tool for tightening and loosening nuts and bolts, and / or removing and / or attaching piping, particularly, but not exclusively, to a compression fitting.

[0024] OVERVIEW

[0025] An aspect of some embodiments of the current invention relates to a tool for tightening and / or loosening nuts and bolts. Some embodiments relate to a tool configured for removing and / or attaching piping. Optionally, the tool has the form of a pliers with a distal head including two jaws. In some embodiments, when the jaws are closed, the head of the pliers form a wrench. Optionally, when the jaws are closed, the head forms a two-sided wrench. Defining up and down along the axis of the pivot of the jaws on one side of the head (the top side) includes a first wrench and the other side of the head (e.g., the bottom side) includes a different second wrench. For example, the top of the head may contain a point to point (e.g., hexagonal) wrench and the bottom of head may contain a multi-point (e.g., double hex socket) wrench. For example, the wrench on the top of the head may fit the same size fastener as the wrench on the bottom of the head. Optionally, the wrench on the top of the head is coaxial with the wrench on the bottom of the head.

[0026] For the sake of the current disclosure, pliers are a hand tool comprising a pair of proximal handles connected by a joint (e.g., the joint may include a simple pivot and / or sliding pivot (e.g., a slip-joint) and / or a linkage (e.g., a tongue and groove linkage)), facilitating the transmission of force to a head that includes a pair of distal jaws. The handles and jaws form a single mechanicalassembly in which force applied at the handles is transmitted through the joint to position, close and / or secure the jaws. These jaws are typically designed to grip, twist, bend, or cut materials, with the joint serving as a fulcrum that amplifies the user's manual force. The handles may be covered with a material that increases grip and comfort, while the jaws may vary in shape and size to accommodate different tasks and materials.

[0027] In some embodiments, slip-joint pliers feature an adjustable pivot point that allows the jaws to open to different widths, accommodating various sizes of objects. This adjustability is facilitated by a slot in one of the handles, through which the pivot bolt can slide. Alternatively, vice grips, also known as locking pliers, include a mechanism that locks the jaws in a closed position, providing a secure grip that can be released by a lever or trigger. This locking feature may be particularly useful for tasks requiring sustained pressure without continuous manual effort.

[0028] Simple pivot-joint pliers, in contrast, have a fixed pivot point, which may offer a straightforward design for consistent gripping tasks. These pliers often have straight jaws, but in some cases, they may feature angled jaws to increase access to tight spaces or awkward angles. Additionally, wrench pliers can be designed with jaws that resemble an adjustable wrench, facilitating the gripping and turning of nuts and bolts. Each type of plier may be tailored to specific applications, with variations in jaw shape, handle length, and material composition to suit particular user needs and preferences.

[0029] For the sake of this disclosure, a wrench is a hand tool designed for gripping, fastening, turning, or loosening objects, typically a fitting for example a nut and / or a bolts head. Handles of the wrench provide mechanical advantage and torque to apply force to the object engaged by the wrench head. The head includes a jaw or socket that fits around the object being manipulated.

[0030] In some embodiments of the current embodiments, a wrench head may exhibit a closed- loop design that encircles a fastener or an open ring that partially encircles fastener from 3, 4 or 5 directions. The internal profile of the wrench head may have the same number of points and flats as the fastener or it may have more flats and points. For example, a fastener for a square fastener may have four or eight flats and / or corners aligning with the flats and corners of the fastener. For example, a fastener for a hexagonal fastener may have six or twelve flats and / or corners aligning with the flats and corners of the fastener. For example, the encircling mayfacilitate the application of torque evenly across the fastener surfaces, potentially reducing the risk of rounding the corners. Wrenches of the current invention may feature straight or offset handles, which can offer improved access to fasteners in tight or recessed spaces.

[0031] In the current disclosure, a coordinate system for wrench pliers will be defined by referencing the geometry of the wrench head and the axis of rotation of the fastener it engages. The longitudinal Z-axis is aligned with the handle direction', the positive Z-direction extends away from the wrench head, along the length of the handle, while the negative Z-direction points toward the fastener. This axis is perpendicular to the axis on which the fastener rotates, and it represents the primary direction of force applied by the user when pulling or pushing the handle to rotate the fastener.

[0032] The lateral axis (X-axis) extends between the two jaws in the plane of the pliers, especially the gap (slot) characteristic of flare-nut wrenches. The gap allows the wrench to pass over tubing before engaging the nut. The positive X-direction is chosen to point outward through this opening in the wrench head, while the negative X-direction points toward the solid jaw region directly opposite the slot. This axis therefore describes movements or forces parallel to the plane of the wrench head but perpendicular to the handle.

[0033] The Y-axis is oriented normal to the plane of the wrench head and perpendicular to both the handle and the open-jaw direction. The positive Y-direction points “up,” away from the top face of the wrench head, and the negative Y-direction points “down,” toward the bottom face. This axis is relevant when describing forces that lift or press the wrench relative to the fastener, or when analyzing the wrench in a three-dimensional spatial model. The fastener’s axis of rotation is perpendicular to the plane of the wrench head and therefore is aligned with the Y-axis. For the sake of this disclosure, we will also refer to the axis of rotation of a fastener rotated by the wrench as the axis of rotation of the wrench.

[0034] For the sake of the current disclosure, engagement surfaces are the internal flats or sides of the wrench head (the box or the jaws) that press directly against the flats of the fitting. The engagement points, often synonymous with the wrench's point count (e.g., 6-point, 12-point), are the corners or vertices of the internal wrench geometry where two engagement surfaces meet. While a 6-point wrench engages all six flats of a hexagonal fitting for increased surface contact and torque transfer, a 12-point wrench engages the fitting using only twelve corners, whichallows for easier positioning but transfers force over a smaller, less secure area.

[0035] For the sake of this disclosure, a "multi-point wrench" refers to a tool designed to engage and turn fasteners, such as bolts or nuts, by contacting them at multiple points around their periphery. Herein, a multi-point wrench has more contact points than the fastener itself, which can facilitate gripping a fastener with more angular freedom is tight spaces. Examples of multipoint wrenches include double square (8-point), double hex (12-point), and 18-point wrenches. The geometry of these wrenches is characterized by a series of internal angles and flat surfaces that correspond to the external geometry of the fastener, allowing for multiple points of contact. In some embodiments, the internal profile of the wrench may be designed to engage fasteners with a specific number of sides, such as squares or hexagons.

[0036] Alternatively or additionally, flare-nut wrenches may be considered a type of multi-point wrench, even though they may not have all the contact points due to a cut-out section. This cutout section allows the wrench to slip over a pipe or tubing, making it suitable for use with flare nuts. Despite the gap, flare-nut wrenches can still provide multiple points of contact on the remaining surfaces of the fastener, facilitating effective engagement and rotation. The geometry of flare-nut wrenches is typically designed to partially enclose the fastener, providing a balance between accessibility and grip.

[0037] For the sake of this disclosure, a "point-to-point wrench" will mean a wrench that has a number of contact surfaces equal to that of the fastener. For example, a 4-point wrench may be used with a square head fastener, and a 6-point wrench may be used with a hex head fastener. These wrenches are designed such that each internal surface of the wrench corresponds to a side of the fastener, facilitating a snug fit and effective torque application.

[0038] Optionally, the piping may be a gas tube, water tube, hydraulic lines, fuel lines, brake lines, power steering lines, refrigerant lines, air conditioning lines, compression fittings, heating lines, ventilation tube, etc. The tool is a double-headed too. The tool is a combined tool.

[0039] According to some embodiments, the tool may include a pair of levers joined at a joint (e.g., including a fulcrum) positioned closer to one end of the levers, creating a head with short jaws on one side of the fulcrum, and longer handles on the other side. This arrangement creates a mechanical advantage, allowing the force of the grip strength to be amplified and focused on an object with precision. The jaws may be used to manipulate objects too small or unwieldy to bemanipulated with the fingers. Optionally, the tool may be configured for loosening and / or tightening nuts and / or bolts. Optionally, the tool may be configured for attaching and / or removing pipes via a connector. According to some embodiments, the tool may include a pair of handles, a fulcrum, and the head section with gripping jaws and / or cutting edges. Optionally, the joint may include a rivet serving as a fulcrum.

[0040] According to some embodiments, the inner surface of the gripping jaws of the head, when brought together, may define the shape of a box-end wrench and / or ring spanner.

[0041] According to some embodiments, the gripping jaws, when brought together, may surround the fastener. Optionally, the head may be circular. The gripping jaws, when brought together, define a gripper on the inner surface configured to grip a fitting, e.g., nuts used in compression fittings and / or other water and / or gas tubing and / or electrical connections. Optionally, the gripper jaws may include multiple engagement points. Optionally, the engagement points may be configured for gripping fittings. Optionally, the engagement points may be broached. Optionally the broached engagement points may be forged and / or cast and / or milled and / or ground. Optionally, the tools may be configured for use when pressurized fluid lines meet various other components, as they prevent damage to the fitting (e.g., flare nut), which may be made of softer metals than a standard bolt head.

[0042] According to some embodiments, the tool may be double-sided. Optionally, the tool may be a combination tool. Optionally, the head may be double-sided. The head may include gripping jaws with two different inner surfaces. The inner surfaces may have a different number of internal engagement points. For example, a first side may have a point to point (e.g., hexagon) shape and a multi-point (e.g., double-hex) shape on the second side. Optionally, the different inner surfaces may be arranged concentrically along the axis of rotation of the wrench. Optionally the inner surface may be configured to grip the same size fastener. Optionally, there will be an opening between the closed jaws of the tool. For example, the opening may pass through both inner surfaces and / or facilitate the tool being used to grip and / or rotate a tube fitting. Advantageously, this design may facilitate the versatility of the tool. Optionally, the two sets of inner engagement surfaces may be coaxial e.g., forming coaxial wrenches.

[0043] According to some embodiments, the tool may include an inner wall. Optionally, the inner wall may be configured to separate the two inner surfaces. Optionally, the inner wall may beconfigured to facilitate the correct positioning of the selected inner surface over a nut and / or bolt and / or pipe and / or connector. Optionally, the inner wall may provide a barrier and / or stopper to facilitate the correct positioning of the selected inner surface over a nut and / or bolt and / or pipe and / or connector. Optionally, the inner diameter of the inner wall may be smaller than the inner diameter of the closed gripper jaw surfaces. Optionally, the inner diameter of the inner wall may range between about 10 mm to about 15 mm, and / or about 15 mm to about 20 mm, and / or about 20 mm to about 25 mm, and / or about 25 mm to about 30 mm, or larger. Optionally, the inner wall may have a thickness ranging between about 0.5 mm to about 1 mm, and / or about 1 mm to about 2 mm, and / or about 1.5 mm to about 3 mm. Optionally, an opening may pass through the closed jaws, the two inner surfaces and / or the inner wall of the tool facilitating using the tool to grasp and / or rotate tube fittings.

[0044] According to some embodiments, the head may be double-sided. Optionally, the two sides may be separated by an inner wall. The head may be sized to include both sides and, optionally, the inner wall. Optionally, the head may have a height ranging between about 10 mm to about 20 mm, and / or about 20 mm to about 50 mm, and / or about 15 mm to about 30 mm. Optionally, the sides may have an equivalent height within the head. Optionally, one side may have a larger head height then the other side within the head.

[0045] According to some embodiments, the point to point-shaped side may be used for tightening and / or loosening nuts and / or bolts. Optionally, the point to point-shaped side may be used for tightening into a final position and / or loosening nuts from a secured position. Optionally, the point to point-shaped side may lock the nut on each side, and / or provide an exact fit, and / or facilitate the exertion of strength on the nut without the tool slipping. The point to point-shaped side may include 6 engagement points. The 6 engagement points may require a minimum swing of 60° to engage the next set of points and / or the next flat side of a standard hex nut (which has 6 sides). Optionally, the cross-section of the head when the gripping jaws are closed may be a hexagon. The gripping jaws may form a closed hexagon with a break to allow the line and / or pipe and / or nut and / or bolt to pass through. Advantageously, since the most common and preferred type of nut has 6 sides, the point to point-shaped side may provide increased contact and grip. Further advantageously, the point to point-shaped side may have less chance of rounding off a soft brass and / or aluminum nut and / or may concentrate the force on the flat sides of the nut. Optionally, the point to point-shaped wrench may not be fully enclosed, allowing it to slip over the tube and / ornut and / or bolt.

[0046] According to some embodiments, the multi-point side may be used for rapid threading. Optionally, the multi-point wrench side may include more than 6 engagement points, e.g., 12 engagement points, 24 engagement points, etc. Optionally, the multi-point side may include 12 engagement points. Optionally, the cross-section of the head when the gripping jaws are closed may be a dodecagon (a 12-sided polygon). The gripping jaws may form a closed dodecagon with a break to allow the line and / or pipe and / or nut and / or bolt to pass through. Optionally, the 12 internal engagement points may be configured to grip the six corners of a standard hexagonal (hex) nut or bolt head. The 12-point multi-point wrench may require a minimum swing of 30° to engage the next set of points on a standard hex nut (which has 6 sides). In some embodiments, some of the engagement points may be missing, for example when there is a gap between the jaws when the wrench is closed. For example, a hexagonal wrench may have only 4 only 5 of the 6 engagement surfaces and / or points. For example, a double-hex wrench may include only 6 and / or only 7 and / or only 8 and / or only 9 and / or only 10 and / or only 11 of the 12 engagement points and / or surface. Advantageously, this minimum swing may facilitate use when working in tight and / or confined spaces where a larger swing is not possible and / or is difficult. Further advantageously, the 12-point multi-point wrench may be easily and / or quickly fitted over a nut. Optionally, the multi-point wrench may not be fully enclosed, providing more gripping surface than an open-end wrench while allowing it to slip over the tube and / or nut and / or bolt.

[0047] According to some embodiments, the head may be sized to fit commonly used nuts, and / or bolts and / or water tube connections and / or gas tube connections. Optionally, the inner crosssection of the inner surface may be larger than the inner diameter of an inner wall separating a point to point (e.g., hexagonal)-shaped gripping surface from a dodecagon-shaped surface. Optionally, the inner diameter of the various gripping surfaces may range between about 10 mm to about 15 mm, and / or about 15 mm to about 20 mm, and / or about 20 mm to about 25 mm, and / or about 25 mm to about 30 mm, or larger.

[0048] According to some embodiments, the tool may include a pair of handles. The handles may be straight and / or offset and / or angled. Optionally, the head and the handles may be aligned.

Optionally, the handles may be sized to be comfortably held by the user. Optionally, the handles may be sized to fit the hands of the user. Optionally, the handles may have a length (from the end to their connection point with the head) ranging between about 5 cm to about 15 cm, and / or about 10 cm to about 20 cm, and / or about 20 cm to about 30 cm.

[0049] According to some embodiments, the tool may include a releasable locking mechanism. Optionally, the locking mechanism may be configured to hold the tool in the desired location and / or with a desired compressive force. Optionally, the locking mechanism may be located on and / or within and / or attached to one or both of the handles. Optionally, the locking mechanism may be located on and / or within and / or attached to the fulcrum.

[0050] According to some embodiments, the tool may include a ratchet. Optionally, the ratchet may be located on the handles of the tool. Optionally, the ratchet may include an internal mechanism configured to allow the user to turn the nut without removing the wrench after each rotation.

[0053] Advantageously, according to some embodiments, the tool may be a convenient tool for use in tightening and / or loosening nuts and / or bolts, and / or for removing and / or attaching pipes. The tool may facilitate rapid tightening and / or loosening and / or removing and / or attaching. Optionally, use of the tool may increase the speed with which a user may tighten and / or loosen nuts and / or bolts, and / or remove and / or attach pipes. The present invention successfully addressesthe shortcomings of the presently known configurations by providing a specialized tool to replace the existing wrenches.

[0054] SPECIFIC EMBODIMENTS

[0055] Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not necessarily limited in its application to the details of construction and the arrangement of the components and / or methods set forth in the following description and / or illustrated in the drawings and / or the Examples. The invention is capable of other embodiments or of being practiced or carried out in various ways. Explanations of possible mechanisms of effect are not intended to limit the invention to a particular theoretical framework.

[0056] Reference is now made to the figures

[0057] FIGs. 1A-D are schematic diagrams illustrating various views of an exemplary wrench with the box-end-shape head in the proximal position, in accordance with some embodiments. Optionally, the tool may be double-sided. Optionally, the tool may be a combination tool. For example, the head 16 of the tool may be double-sided. The head 16 may include gripping jaws 17a, 17b with two different inner surfaces. For example, an upper side 14of the jaws 17a, 17b may have a multi-point (double-hex) geometry. Optionally, the two sets of inner engagement surfaces may be coaxial e.g., forming coaxial wrenches. For example, the two wrenches may be sized to grasp the same size fitting. In some embodiments, the inner surfaces of each of the two wrenches may have a different number of internal engagement points. For example, one of the wrenches may have a point-to-point wrench (e.g., hexagonal-shaped inners surface) on a lower side 18 of the head and a multi-point (e.g., double-hex) wrench on the opposing upper side 14.

[0058] For the sake of clarity, a set of axes is defined. The origin of the axis is defined on the axis of rotation of the tool in the middle of the head. A longitudinal z-axis is defined along a line joining the fulcrum of the tool (on the joint 8 thereof) to the axis of rotation of the tool. The positive longitudinal direction is from the proximal (handle 10) end of the tool toward the distal (head 16) end of the tool. The lateral x-axis is defined perpendicular to the longitudinal axis along the direction of movement of the jaws of the tool. A vertical y-axis is defined perpendicular to the x-and z- axis. The vertical y-axis is the axis of rotation of the tool.The multi-point side 14 may be used for rapid threading.

Alternatively or additionally, even in the closed configuration there may be a break to allow the line and / or pipe and / or nut and / or bolt to pass through. Optionally, the 12 internal engagement points may be configured to grip the six corners of a standard hexagonal (hex) fitting. The 12-point multi-point wrench may swing of 30° to engage the next set of points on a standard hex fitting (which has 6 sides). Advantageously, this short swing between contact points of the multi-point configuration may facilitate use when working in tight and / or confined spaces where a larger swing is not possible and / or is difficult. Further advantageously, the 12-point multi-point wrench may be easily and / or quickly fitted over a fitting. Optionally, the multi-point wrench may fully or partially enclose a fitting (e.g., providing more gripping surface than an open-end wrench while allowing it to slip over the fitting.

[0059] The head 16 may be sized to include both sides and, optionally, an inner wall 12. The tool may include an inner wall 12. Optionally, the inner wall may be configured to separate the two inner surfaces. Optionally, the inner wall may be configured to facilitate the correct positioning of the selected inner surface over a fitting (e.g., nut and / or bolt and / or connector). Optionally, the inner wall may provide a barrier and / or stopper to facilitate the correct positioning of the selected inner surface over a fitting. In some embodiments, there is an opening 13 through the head of the wrench that may be positioned around a pipe and / or a tube. For example, the inner wall may surround the opening 13. Optionally the axis of the wrench passes through the opening 13. Optionally, the inner surface 15 of the inner wall may define the opening and / or may be smaller than the inner diameter of the closed gripper jaw surfaces. Alternatively or additionally, the closed gripper jaw surfaces of the wrench may define the outer edges of the opening 13 through the wrench.

[0060] The tool may include a pair of handles 10 joined by a joint 8, e.g., a rivet serving as a fulcrum. The handles may be straight and / or offset and / or angled. Optionally, the head and the handles may be aligned. Optionally, the head may be bent at an angle to the handles ranging between about 15° to about 45°. Optionally, the head may be offset to the handles to facilitateknuckle clearance and / or reaching recessed fittings and / or obscured fittings.

[0073] FIG. 4 is a flow diagram illustrating an exemplary use of an exemplary tool, in accordance with an embodiment of the current invention. For example, in method 60, the tool is double sided, having a point to point (e.g., hexagon shape) on one side and a multi-point shape (e.g., double hex) on the other side. The multi-point side is placed over a fitting, and closed 62. Optionally, the tool is kept in place and / or closed 62 by hand.

For example, the point-to-point side of the tool may be Optionally, the tool may include a ratchet for increasing the speed of the user.

[0075] Fig. 5 is a block diagram of a point-to-point pliers wrench in accordance with an embodiment of the current invention. In some embodiments, the combination tool described herein comprises two handles 542 that are joined by a joint 544. This joint serves as a pivotal connection, facilitating the transfer of force from the handles to the jaws 546 located distally. The joint may include various types of pivots, such as a simple pivot, a slip-joint, or a linkage like a tongue and groove, which allows for adjustable movement and enhanced force transmission. The handles are designed to provide a comfortable grip and may be covered with materials that enhance grip and comfort, such as rubber or thermoplastic elastomers.

[0076] The jaws 546 of the tool are distal to the handles and optionally include engagement surfaces 548. 550 configured to engage a fitting. For example, when the jaws 546 are closed, each set of contact surfaces 548, 550 forms a wrench. Each jaw includes a portion of each of a first set of engagement surfaces 548 and a second set of engagement surfaces 550. These engagement surfaces are specifically designed to accommodate different fittings, such as rotary connectors, nuts and bolts, providing versatility in application. The jaws are designed to close and secure around the fitting, with the joint acting as a fulcrum to amplify the user's manual force.

[0077] In some embodiments, the first set of engagement surfaces 548 may include at least two surfaces on each jaw, allowing for a secure grip on the fitting. This configuration is particularly useful for engaging fittings with multiple sides, such as hexagonal nuts. The second set of engagement surfaces 550 may also include at least two surfaces on each jaw, providing additional gripping options. This dual-surface design enhances the tool's adaptability to various tasks and fittings.

[0078] Optionally, the engagement surfaces are located on the inside surfaces of the jaws 546, facilitating a secure grip on the fitting when the jaws are closed. In some embodiments, theengagement surfaces of one jaw are parallel to the opposing engagement surfaces of the other jaw when the jaws are closed, ensuring a precise and even grip on the fitting. This parallel alignment is particularly advantageous for maintaining stability and reducing the risk of slipping during operation.

[0079] In some embodiments, the two different sets of engagement surfaces are coaxial, meaning they share a common axis. For example, the two sets of engagement surfaces 548, 550 may be coaxially arranged along a vertical axis of the jaws 546, allowing for easy access to fittings when the jaws are open and / or tight fit to the fitting when the jaws 546 are closed.

[0080] The jaws 546 may close by approaching each other along a lateral axis, which is perpendicular to the longitudinal axis of the handles. This lateral movement facilitates the tool's ability to grip and manipulate fittings with precision. In some embodiments, the tool is designed to engage the same fitting with both sets of engagement surfaces, for example, providing a point-to-point wrench on one side and a multi-point wrench on the other.

[0081] The point-to-point wrench configuration, formed by one set of engagement surfaces, is designed to engage fittings with a specific number of sides, such as hexagonal nuts. This configuration provides a snug fit and effective torque application, reducing the risk of rounding the corners of the fitting. The multi-point wrench configuration, formed by the other set of engagement surfaces, offers more contact points than the fitting itself, facilitating gripping with more angular freedom in tight spaces.

[0082] In some embodiments, the multi-point wrench forms a hexagonal socket when the jaws are closed, providing a secure grip on hexagonal fittings. This design is particularly advantageous for rapid threading and unthreading of fittings, as it requires less swing to engage the next set of points on the fitting. The tool may also include an inner wall that separates the two sets of engagement surfaces, providing a barrier to facilitate the correct positioning of the selected surface over the fitting.

[0083] The tool's construction may involve forging, casting, milling, or other manufacturing processes, and it may be composed of durable metals such as chrome vanadium steel or stainless steel. Optionally, the tool may be coated with materials like chrome plating or black oxide to enhance durability and corrosion resistance. The handles may be ergonomically designed to fit comfortably in the user's hand, with optional features like a releasable locking mechanism or aratchet to enhance functionality and ease of use.
