Three Piece Coupling, 1/2 in, Malleable Iron

1/2 in three piece couplings are used to connect 1/2 in threaded rigid or IMC conduits that are not able to be turned. Garvin Industries' three piece couplings provide concrete tight connections. Garvin Industries' heavy gauge construction maintains mechanical protection and solid grounding of one conduit to another. Three piece couplings are zinc electroplated for excellent corrosion protection in damp locations.
