Thomas & Betts 8720 Conduit Compression Coupling

Description:

The Thomas & Betts 8720 Non-Insulated Threadless Compression Coupling AK is used to join 2-1/2 inch rigid metal conduit (RMC) or intermediate metal conduit (IMC) while providing a secure mechanical connection and electrical bonding without requiring conduit threading. Commonly installed in industrial facilities, manufacturing plants, commercial buildings, utility systems, and electrical distribution installations, this compression coupling simplifies conduit installation in confined spaces. Maintenance teams and electrical contractors use this fitting for repair, retrofit, expansion, and replacement of rigid conduit systems.

Applications:

The Thomas & Betts 8720 is designed to couple 2-1/2 inch rigid metal conduit and IMC where neither conduit length can be rotated during installation. Its threadless compression design eliminates the need for field threading while providing a concrete-tight connection and dependable grounding continuity. The coupling is suitable for switchgear, motor control centers, industrial machinery, commercial electrical systems, and utility raceway installations requiring durable conduit connections.
