Value Brand 3LW93 1" Male Adapter x FNPT 316 SS Coupling

SKU CH-QJX7-QG9CF

A 316 stainless steel cam-and-groove adapter with 1 inch FNPT threads rated to 250 psi at 70 F

  • 316 stainless steel body resists corrosion in harsh environments
  • Type A cam-and-groove design enables quick tool-free connections
  • 1-inch NPT female thread fits standard plumbing pipe sizes
  • Rated for 250 psi maximum working pressure at 70 F
  • Compact 1-29/32 inch overall length suits tight installation spaces

1-Inch Stainless Steel Cam-and-Groove Adapter

This 316 stainless steel adapter connects a 1-inch male cam-and-groove plug to a 1-inch female NPT thread. It suits fluid-transfer systems that require corrosion-resistant couplings in chemical, food-grade or marine environments. The Type A configuration provides a secure, tool-free connection for hoses or rigid piping. Buyers needing a different thread standard or a non-stainless body should look elsewhere.

Pressure Rating and Operating Temperature

The fitting is rated for a maximum working pressure of 250 psi at 70 degrees Fahrenheit. Stainless steel construction resists internal pressure without deformation and maintains seal integrity across typical ambient temperature ranges. No moving parts or seals generate noise, and the adapter draws no power in any installation.

Thread Size and Connection Type

The adapter uses a 1-inch minus 11-1/2 NPT female thread paired with a 1-inch cam-and-groove hose fitting. This specific thread pitch and coupling style determine whether the part matches existing plumbing. Verify both the thread standard and the cam-and-groove type before ordering.

Questions about this item

How do I install the 1 in -11-1/2 NPT threads on this 316 stainless steel adapter, and what step do people often miss?

Wrap PTFE tape clockwise on the male threads, engage the 1 in FNPT connection by hand, then tighten one to two turns with a wrench; the common error is over-tightening and cracking the female port.

What maintenance or replacement will this cam and groove adapter need over time?

Inspect the 316 stainless steel body and locking arm for corrosion or wear; replace the adapter if threads show galling, the plug outside diameter deforms, or the sealing face leaks.

What is the first limit reached under sustained use at the 250 psi rating and 70 F temperature?

The 250 psi maximum working pressure at 70 F is the primary limit; exceeding it risks permanent deformation of the 1 7/16 in plug outside diameter or thread failure.
