The disclosure is directed to a pre-assembled liquid tight connector for use with flexible metallic conduit. The connector is comprised of a one piece body member having a grounding member formed integrally therewith. Additionally, the body member is so constructed as to retain a resilient polyurethane collar in a pre-loaded position so that after assembling the ground conductor to the flexible metallic conduit, the collar is simply pried from the pre-load position and a liquid tight seal is achieved.

A liquid tight connector for coupling metallic flexible conduit to an electrical enclosure comprised of: an electrically conductive connector body and a resilient collar mounted thereon, each having an axial passage therethrough, said connector body having a first end adapted for coupling said connector body to an electrical enclosure, a shoulder portion adjacent said first end and a second end adjacent said shoulder portion for coupling said connector body to said conduit, said second end having spaced apart concentric first and second projections, said first projection dimensioned to be received in said conduit and having a spiral ridge thereon for engaging the interior of said conduit, said second projection dimensioned to surround said conduit and having at least one exterior rib spaced from said shoulder on the surface thereof, said resilient collar having in a relaxed state a diameter of said passage which is less than the diameter of said second projection, and further having a first internal ridge at one end thereof, a second internal ridge proximate the other end thereof and a tapered rib forward of said second internal ridge and remote from said first internal ridge, said tapered rib having an internal diameter less than the external diameter of said conduit and said second internal ridge having an internal diameter less than the external diameter of said second projection in the relaxed state of said collar, said collar mounted on said second projection with said first internal ridge positioned between said shoulder portion and said exterior rib and said second internal ridge positioned forward of said exterior rib whereby after threading said conduit onto said spiral ridge said resilient collar is urged away from said shoulder portion and toward said exterior rib until said second internal ridge dismounts said second projection and said first internal ridge abuts said exterior rib thereby allowing said resilient collar to compress inward toward its relaxed state and said tapered rib to engage the exterior surface of said conduit.
