GROMMET FOR A CABLE CONNECTOR AND A STRAIN RELIEF CABLE FITTING HAVING AN INSERT
A grommet for use in a cable fitting includes a body having a bore substantially therethrough and a resilient membrane located within the bore. The resilient membrane is elastically deformable from a receiving position before the cable is inserted into the bore, to an inserted position, after the cable is fully inserted into the bore. In the receiving position, the resilient membrane is substantially conically shaped having an apex substantially coincident with an insertion opening of the body, and, the resilient membrane is axially displaced during the insertion of the cable to an inverted position with respect to the receiving position where the apex is oriented away from the insertion opening. The resilient membrane has a thinner membrane portion extending from the apex towards the bore to provide a controlled tear during cable insertion. The body has an exit opening which comprises resilient gripping teeth projecting axially from the body with an axially extending resilient foldable membrane located between at least two adjacent resilient teeth and foldable therebetween when they are radially compressed. Once force is applied by the axial movement of the fitting assembly onto a tapered surface of the grommet, the flexible gripping members radially collapse towards an inserted cable. The combination of the resilient membrane and the axially extending teeth separated by a foldable membrane allow for an increased friction fit and sealing interface on the cable. The grommet may be assembled in a strain relief connector having a nut, a connector body and optionally an insert. The insert has a removed section longitudinally coincident with a gripping surface facilitating movement of the gripping surface towards the cable.

THERMAL EXPANSION COMPENSATING DEVICE AND METHOD OF USE
A thermal expansion compensating device has a conduit with a first opening and a second opening for connection to a first pipe and a second pipe of a hot water system, respectively, the first and second pipes being formed by removing a section from a length of pipe of the hot water system. A pre-tensioning force is applied to the device to axially displace the first opening from the second opening until after connection of the openings of the pipes. A resiliently deformable pipe segment defines a portion of the conduit between the first opening and the second opening and is resiliently deformed to a tensioned position by the application of the pre-tensioning force. Once the hot water system is activated, the pipes axially thermally expand such that the first opening moves towards the second opening and the pipe segment moves from the tensioned position towards a rest position decreasing the stress on the device.
A heat exchanging to exchange heat between a first fluid and a second fluid has a thermally conductive conduit with a double wall construction with an inner wall and an outer wall fixed thereto and defining a plurality of leak channels therebetween.
