Abstract:
A sealing ring having a flexible ring body and a front and rear seal separated by a channel and a set screw recess adjacent one end. The sealing ring is placed on the end of a set screw electrical fitting or connector and forms a seal between the body of the set screw electrical fitting or connector and the exterior surface of an electrical conduit. The sealing ring prevents concrete from entering a gap formed between the body of the set screw electrical fitting or connector and an electrical conduit during pouring of concrete. Concrete entering the gap may interfere with electrical connections.
