Electrical conduit coupling devices are disclosed that include a casing formed of a steel tubing that, in turn, includes a rear portion and a front portion, an elastomeric 'O' ring secured at the front portion by a retainer and an end cap. The electrical conduit coupling devices further include a clamp that is arcuate in shape, and in one embodiment, has ends separated from each other to form a gap therebetween which is diametrically located opposite a cut-out in the central region of the clamp. The cut-out cooperates with the separated ends to allow the clamp to clamp around a conduit that is inserted into the electrical conduit coupling device. The electrical conduit coupling devices provide for not only rigid connection to a conduit, but also a waterseal or concrete seal connection therebetween.

Electrical fitting for conduit connection

An angularly adjustable angularly adjustable electrical conduit fitting includes an articulate metal conduit bendable at least 90 degrees about an arc having an inside radius of curvature not exceeding 12 inches, the conduit in its preferred from being between 19 3/4 and 20 3/4 inches long in a contracted state and being extendable by between 21% and 23% of its contracted length and having at one end a conduit coupling and at its opposite end a conduit or wall opening connector.

Armored flexible electrical conduit with fittings

Electrical connector

A strain relief electrical cable fitting includes an externally threaded metal tubular body member divided by an inside inclined shoulder and outside flange into an upper compression chamber and a lower coupling section, a gland cap with a central top opening engaging the body member top thread. Housed in the compression chamber is an assembly of a rubber packing member and a metal grip member, the packing member including an upper axially bored cylindrical section and peripherally spaced longitudinal fingers and the grip member including an upper ring encircling the packing fingers and abutting the cylindrical section underface and depending metal longitudinal fingers swingable about the ring and interdigitating the packing fingers and terminating in follower sections engaging the shoulder so that tightening of the cap compresses the packing member by way of a washer to advance and contract the grip fingers to clamp and ground a fitting engaged metal armored cable and to contract the packing section bore and effect a hermetic seal of the cable. The inside faces of the grip fingers delineate a circular or polygonal axial bore.

Strain relief liquid tight electrical connector

A strain relief electrical cable fitting includes an externally threaded tubular body member divided by an inside inclined shoulder and outside flange into an upper compression chamber and a lower coupling section, a gland cap with a central top opening engaging the body member top thread. Housed in the compression chamber is an assembly of a rubber packing member and a nylon grip member, the packing member including an upper axially bored cylindrical section and peripherally spaced longitudinal fingers and the grip member including an upper ring encircling the packing fingers and abutting the cylindrical section underface and longitudinal fingers interdigitating the packing fingers and terminating in follower sections engaging the shoulder so that tightening of the cap compresses the packing member by way of a washer to advance and contract the grip fingers to clamp a fitting engaged cable and to contract the packing section bore and effect a hermetic seal of the cable.
