A low odor grip is disclosed for a handle of a hand-held implement such as a sports implement or a manual or electric tool which is essentially free of disagreeable odors, which can be installed and quickly shrunk into a tight vapor resistant grip within a matter of a few minutes rather than requiring extended periods of time, and can be installed without the need for any application of heat or use of special tools, equipment or materials. The present device is therefore easy to install, merely sliding over the handle while in dilated state and then allowed to shrink and set by evaporation of the solvent, and thus can be satisfactorily installed in both fabrication facilities and in the field either as an original or replacement grip. The invention also includes an implement fitted with such grip. Representative implements include sports implements such as golf clubs, tennis racquets, weight bars and fishing poles, as well as tools such as hammers, drills, pliers, shovels, axes, and the like. The grip is preferable made of a swellable elastomeric material, preferably a natural or synthetic rubber. Suitable rubbers include EPDM rubber, neoprene or chlorosulfonate polyethylene (Hypalon(TM)) rubber, of which EPDM rubber is preferred.

An insulator bushing wildlife guard having features for easier alignment and installation of the guard on the bushing. The guard has two hinged body sections of insulating material. An outer edge of each body section is provided with a plurality of flexible fingers that allow conductors to pass through from the interior to the exterior of the enclosure when the two portions of the guard are engaged. In one embodiment, the guard is spring biased toward a closed position. A handle on the back has inner grooves to make it easier to grasp and manipulate the guard using a shotgun stick. On a lower front side of each portion of the guard, spaced-apart, curved, horizontal upper and lower flanges help align the guard with the topmost skirt of a bushing.

An external tab limiter, disposed above the upper flange, makes it difficult to install the guard over any part of the bushing other than the topmost skirt of the bushing. An alternative version of the guard has a releasable trigger, which is used to hold the two portions in an open position until the bushing or power line displaces the trigger and allows the biasing spring to close the two cover portions. The guard is provided with a handle for grasping by a manipulator tool. In one embodiment the handle is provided with inner grooves for grasping by a shotgun stick. In another embodiment, an adapter releasably engages the handle and provides means for attachment to a hotstick.

An insulating coating layer is removed in a lengthwise intermediate part of the wire to expose a core. A heat shrinkable tube with an inner layer made of a hot-melt waterproofing agent is mounted on the exposed core section and parts of the insulating coating layer adjacent to the exposed core section and heated. As a result, the hot-melt waterproofing agent of the inner layer is melted and infiltrates into clearances between strands of the exposed core section. In addition, negative pressure is introduced into the inside of the insulating coating layer from an end of the wire, thereby sucking the waterproofing agent into the inside of the insulating coating layer to infiltrate the waterproofing agent also between the strands of the core inside the insulating coating layer.

An integrated seal assembly and a coaxial cable system component incorporating the seal assembly with a connector for coupling to an externally threaded port. The seal assembly includes a bellows-type seal having an elastically deformable tubular body and a plurality of sealing surfaces, and an integral joint-section intermediate an anterior end and a posterior end that assists in the axial deformation of the seal in response to axially-directed force. One of the sealing surfaces is made to engage a corresponding surface of an internally threaded nut or housing.

The anterior end of the seal fits over the port and a sealing surface of the seal is capable of sealing axially against a shoulder of the port while the seal body covers the otherwise exposed externally threaded port. Upon tightening of the nut on the port, the seal deflects in the axial direction to accommodate a variety of distances between the connector and the shoulder of the port. Additionally, the seal is capable of expanding to allow a second sealing surface to contact and seal against a variety of smooth outside diameters of the port. The versatility of the seal allows an operator to use one connector of a system component on a wide variety of externally threaded ports without the risk of a faulty seal at the connection or a poor connection due to an improper seal.
