Hazardous Location Conduit Unions, Expansion Unions & Nipples
These unions, expansion unions, and nipples join pieces of heavy-wall RMC and medium-wall IMC metal conduit together, or join electrical boxes and enclosures in hazardous industrial locations, such as petroleum refineries, gasoline storage areas, and petrochemical facilities. They form a tight seal to protect wire and cable in areas where flammable gases, vapors, powdered metals, or dust is present.
Nipples
Nipples mount through a knockout or hole and lock in place with a locknut, or they thread onto the end of a piece of threaded RMC or IMC conduit and are then inserted into the knockout or hole. They act as a short conduit raceway between two electrical devices, such as enclosures, junction boxes, or fixtures. Nipples are suitable for use in hazardous locations where flammable gases, vapors, powdered metals, or dust is present.
