Industrial 4-inch Union Coupling Conduit Fittings are fittings that join two lengths of conduit in industrial electrical systems using a union-style connection. The 4-inch designation specifies the conduit diameter the coupling is designed to accommodate. This union coupling provides a removable, aligned joint to simplify assembly, disassembly, and maintenance of conduit runs. Suitable for use in various industrial conduit installations where a detachable joint is required, these fittings support a continuous, serviceable conduit path.
