AI Technical Summary

Problems solved by technology

If the installer does not press the fittings properly to provide a permanent seal, fluid can leak causing significant damage and cost
Defects or scars in the inserted tubing also create the possibility of the connection leaking after compression
In many installation situations, the installer will take a work break or be distracted and have difficulty determining which of the multiple press fittings has been properly compressed and which has been improperly compressed or not compressed at all
When this happens, there is no easy and quick way (other than a catastrophic failure or leak) to determine which fittings have been pressed correctly, which can lead to time spent determining which fittings need to be pressed or damaged in the application environment

Embodiment Construction

[0031] Such as Figure 1 to Figure 6 As shown, the present invention provides a fitting 10 having a somewhat cylindrical body member 20 having an inner surface 14 and an outer surface 16 . In one embodiment, body member 20 may be formed (eg, forged, cast, extruded, pressed) from brass, aluminum, steel, malleable iron, or copper, eg, with full port and full flow fittings. The inner surface 14 defines a cavity 18 extending through the body part 20 along a central axis A and including a tube stop 35 extending radially inwardly at approximately the axial midpoint of the part 20 . A tube stop 35 divides the inner surface 14 into a first interior compartment 31 and a second interior compartment 33, and when a tube 25 of appropriate diameter is inserted into the compartments 31, 33, its axial end wall 27 (see figure 1 ) abuts the tube stop 35 so that the tube cannot be inserted further axially into the component 20. It should be understood that embodiments of the present disclosure...

Abstract

A press-fit device, components, and method provide one or more indicators to provide a visual indication that a fitting has been properly pressed about a tube and that the correct amount of pressure has been provided to create a permanent seal. In an embodiment, the invention includes a fitting having a body part with a packaged arrangement including a sealing ring, a locking ring support member, a locking ring and a malleable and expandable indicator ring.

Description

technical field [0001] The present invention relates generally to fluid flow systems, and more particularly to press-fit fittings for visual indicators of fluid flow systems. Background technique [0002] The tubing is used to facilitate the flow of fluids, such as liquids, vapors such as air, or plasmas. For example, homes, schools, medical facilities, commercial buildings and other occupied structures often require integrated plumbing systems so that water and / or other fluids can be circulated for various purposes. Liquids and / or gases such as cold and hot water, breathable air, glycol, compressed air, inert gases, cleaning chemicals, waste water, plant cooling water, and paints and coatings are just a few of the types of fluids and gases deployed through piping systems some examples. Tube / piping types may include, for example, copper, stainless steel, CPVC (chlorinated polyvinyl chloride), iron, black iron, ductile iron, gray iron, HDPE (high density polyethylene) and P...
