316 Stainless Steel IMC Coupling

This half-inch threaded coupling joins rigid and intermediate metallic conduit in electrical installations. The three-piece design uses 316 stainless steel for corrosion resistance in harsh environments. It carries cULus listing and meets UL 514B, CSA C22.2 No. 18.3 and Canadian Electrical Code requirements. Suitable for industrial and commercial wiring projects.

Sustained environment performance

The polished 316 stainless steel finish resists corrosion during long-term exposure to moisture, chemicals and temperature cycling. Threaded female connections maintain mechanical integrity and grounding continuity under vibration and thermal expansion. The coupling remains compliant with NEC and Canadian standards throughout the service life of the conduit run.

Trade size 1/2 inch constraint

This coupling only fits conduit with a 1/2 inch trade size and threaded ends. It cannot connect larger diameters, non-threaded tubing or PVC systems. Installers needing different trade sizes or coupling types must select a separate fitting.

Questions about this item

Does the 316 stainless steel coupling generate heat or noise when installed in conduit running continuously?

The coupling is a passive mechanical fitting with no moving parts or electrical components, so it produces no heat or noise during continuous operation.

What conduit and tools must I already have to use this 1/2 in threaded coupling?

You need 1/2 in trade size RMC or IMC threaded metallic conduit and standard conduit wrenches to tighten the female-threaded connection.

Will this cULus-listed coupling work with my existing RMC and IMC conduit installed under NEC rules?

Yes, it is cULus listed to UL 514B and CSA C22.2 No. 18.3, and complies with NEC and Canadian Electrical Code Part I for use with threaded RMC and IMC.
