1-inch stainless conduit connector

The CALBRITE S61000MC00 is a rigid compression connector made from 316 stainless steel for trade size 1-inch RMC conduit. Its polished finish and NPS threading suit industrial and commercial electrical installations requiring NEMA 4X and UL listed components. The connector measures 2 inches overall with a 1.33-inch inside diameter. It weighs 0.4 lb and is sold new.

Replaces standard fittings in corrosive settings

This connector upgrades from uninsulated carbon-steel or plated fittings where chemical wash-down, salt spray or outdoor exposure degrade lesser alloys. The jump is worth it when the specification calls for 316 stainless to meet NEMA 4X enclosure integrity. It threads directly onto 1-inch RMC using the 11 1/2 thread form without adapters.

Limited to rigid metal conduit only

The fitting accepts only RMC of matching trade size; it does not fit EMT, IMC, PVC or flexible conduit types. The NPS thread profile requires matching conduit threads and cannot join dissimilar raceway systems. Installers must verify conduit compatibility before assembly because the compression design is not interchangeable with set-screw or push-fit bodies.

Questions about this item

What 1 in NPS thread size does the CALBRITE S61000MC00 need for mounting?

The connector uses a 1 In. -11 1/2 NPS thread that mates with standard rigid metal conduit hubs or threaded enclosures.

Which step is often missed when installing this compression connector on RMC?

Tightening the compression nut until the ferrule visibly bites the conduit wall; hand-tight alone will not meet the NEMA 4X seal.

When should the 316 stainless steel ferrule be replaced on this 0.4 lb connector?

Replace it if the ferrule shows deformation, cracking or corrosion after repeated disassembly, otherwise the 316 stainless body and nut are maintenance-free.
