  • Patent number: 8708374
    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.

  • Patent number: 7431343
    Abstract: A joint structure for connecting a corrugated pipe to a fixed part includes a main body, a packing screw cap, and a clamping claw. The clamping claw is sandwiched between the main body and the packing screw cap. The clamping claw defines a through slot at an edge thereof to make the clamping claw can enlarge an inside diameter thereof. A plurality of inner claws is formed at the edge of the clamping claw. A locking part protruding towards the center of the clamping claw is formed at an end of each of the inner claws. Two slits are respectively defined at two sides of each inner claw so that the inner claw has elasticity. The corrugated pipe with different diameters can directly insert into the clamping claw from outside, and the corrugated pipe cannot be dropped out directly.
