Abstract: A liquid-tight fitting is provided to connect generally non-compressible plastic conduit and electrical cable to a connection of some type. The fitting has a self-adjusting rigid plastic gland, which has a body portion with a relatively thin sleeve extending axially away from the body portion for encircling the conduit or cable. A nut threaded on the body of the fitting compresses the sleeve into sealing engagement with the conduit and fitting and to positively interconnect the conduit and connection to provide strain relief therewith.

Abstract: A vapor-proof connector on a metal electrical conduit includes an externally threaded tubular body engaging the end of the conduit and a gland nut spaced inwardly of and engaging the tubular body. The gland nut has an inwardly directed peripheral flange with a tapered inside face confronting a tapered end face of the body to delineate an annular space which surrounds the conduit and houses a channel-shaped split metal ring having inwardly directed diverging flanges and a wedge-shaped deformable gland ring arranged end to end so that tightening of the gland nut compresses the gland ring between the metal ring and the body or nut to radially compress the inside face of the gland ring and cause the split ring to bite and anchor to the conduit. Alternatively, the gland ring may be encircled by the split ring. The ends of the split ring may have opposing reduced width tongues extending therefrom.
