초록

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 gla...
