Conduit fittings are connectors and fittings used to connect one piece of conduit to another, or to connect conduit to an electrical box. They are available in various metals, as well as with different levels of moisture protection. Conduit fittings have two types of joints: Rigid/IMC conduit fittings and EMT fittings. Rigid/IMC conduit fittings are usually in malleable iron or machined steel material or stainless steel.Fittings are galvanized to ensure corrosion resistance When used outdoors or exposed to wet areas. EMT is a lightweight steel conduit with walls that are too thin to be threaded. Set screw and compression fittings are the most popular couplings and connectors followed by our indenters. These fittings have a much lighter weight and are more economical than rigid fittings.Electricians usually select economy grade die cast fittings for EMT unless codes or specifications call for steel.
