3/8 in 316 SS Rod Coupling

The CALBRITE 3/8 in rod coupling is a short, fully threaded connector made from Grade 316 stainless steel. Its plain finish and right-hand threads suit conduit and raceway systems that need corrosion resistance in harsh environments. The small pack format provides a convenient quantity for maintenance or assembly tasks. It joins threaded components securely within the specified system.

Fits 3/8-16 threaded conduit systems

This coupling suits installers joining 3/8 in -16 threaded conduit or fittings where 316 stainless steel is specified for chemical or marine exposure. It is not for metric threads, left-hand threads or larger pipe sizes. Buyers needing a different thread pitch, diameter or material grade should select an alternative fitting.

1 1/8 in overall length with 3/64 in hex

The 1.100 in overall length provides a compact joint for tight conduit runs. The 3/64 in hex width allows engagement with a suitable wrench for assembly. It handles standard mechanical loads for this thread size. The short length limits the number of engaged threads so it is not intended for high-vibration structural connections.

Questions about this item

What thread size must the conduit or rod already have to accept this 3/8 in -16 coupling?

The coupling fits a 3/8 in -16 right-hand thread, so the mating conduit or rod must carry the same thread specification.

Will the 316 stainless steel coupling resist corrosion when paired with older galvanised conduit?

Yes, the 316 stainless steel material provides corrosion resistance and is compatible with galvanised conduit in most environments.

How can I confirm the coupling is fully engaged after installation?

When the hex flats are tight against both conduit ends and no thread is visible, the 1 1/8 in overall length indicates full engagement.
