3-Inch 316 Stainless Coupling

This CALBRITE coupling connects two sections of 3-inch threaded metallic conduit. It is manufactured from 316 stainless steel with a polished finish and weighs 2.25 lb. The fitting meets ANSI/NFPA 70, NEC, UL 6A and UL File #E230584 standards for electrical installations.

Suited For Rigid And IMC Runs

Electricians joining RMC or IMC conduit in corrosive or hygienic environments will appreciate the 316 alloy and UL/CUL listing. The NPS threads accept only threaded metallic conduit, so installers using PVC, EMT or non-threaded systems must select a different fitting type.

Threaded Connection For 3-Inch Conduit

The coupling requires male NPS threads on both conduit ends and provides an inside diameter of 3.5 in for wire pulling. Its overall length of 3 5/16 in and width of 3 25/32 in determine the space needed in the run. No additional hardware or solvent is required for the threaded joint.

Questions about this item

What size and type of threaded metallic conduit must I already have to connect with this 3 in trade-size coupling?

You need rigid metal conduit or intermediate metal conduit with a 3 in trade size and NPS threads to match this coupling.

Will this 316 stainless steel coupling fit onto my existing galvanised RMC or IMC without causing corrosion?

The 316 stainless steel material is compatible with threaded metallic RMC and IMC; dissimilar-metal corrosion risk is low in typical indoor or dry outdoor runs.

How can I verify the coupling meets code after I thread it onto the conduit?

Check for the UL listing mark and file number E230584 on the polished body; the mark confirms compliance with UL 6A and NEC ANSI/NFPA 70.
