THOMAS & BETTS 8320 THREADLESS COMPRESSION COUPLING

Description:

The Thomas & Betts 8320 Threadless Coupling is used to join and effectively bond 1-inch rigid metal conduit (RMC) or intermediate metal conduit (IMC) without the need for conduit threading. Commonly installed in industrial facilities, commercial buildings, utility installations, and electrical distribution systems, this malleable iron coupling provides a concrete-tight connection and simplifies conduit installation where conduit rotation is not possible. Electricians, maintenance technicians, and contractors use this fitting for new installations, repairs, retrofits, and replacement of rigid conduit connections.

Applications:

The Thomas & Betts 8320 is designed to couple threaded ends of rigid metal conduit or IMC where neither conduit length can be rotated during installation. It is also used to connect threadless rigid or IMC conduit to electrical boxes and enclosures, making it ideal for industrial plants, commercial buildings, utility facilities, manufacturing equipment, and concrete-embedded conduit systems requiring a secure, concrete-tight bond.
