A 304 stainless steel cam-and-groove coupler with NPT thread and nitrile gasket rated to 150 psi at 70 °F

  • Product colorTransparent
  • Product typePipes, Valves & Fittings
  • 304 stainless body resists corrosion in wet environments
  • Type D cam-and-groove design enables quick tool-free hose connection
  • 150 psi rating at 70 °F handles typical fluid-transfer pressure
  • 1/2 inch FNPT threads match standard piping without adapters
  • Nitrile gasket seals reliably across common temperature ranges

Cam-and-Groove Coupler for 1/2" NPT Lines

This stainless-steel Type D socket connects to a 1/2 in -14 NPT female thread and accepts a 1/2 in hose fitting. It suits fluid-transfer systems that require a quick-disconnect joint rated for 150 psi at 70 F. The 304 stainless body resists corrosion in water, chemical and food-grade applications.

Pressure Rating and Seal Performance

A nitrile gasket seals the 15/16 in socket bore against the working pressure of 150 psi at 70 F. The coupling has no locking arm, so engagement relies on the cam-lever force alone. Stainless construction handles the rated pressure without deformation under normal thermal cycling.

Installation Fit and Clearance

The overall length is 47.5 mm, keeping the joint compact inside piping assemblies. The 1/2 in NPT thread matches standard pipe sizes without adapters. Builders who need a locking arm or a larger bore must select a different coupling style.

Questions about this item

How do I install the 1/2 in NPT thread on this cam and groove coupler and what step is often missed?

Wrap the 1/2 in -14 NPT threads with PTFE tape, thread into the mating port, then fully close the cam arms until they lock; the step often missed is confirming the nitrile gasket seats evenly in the 15/16 in socket before pressurising.

What maintenance will the nitrile gasket on this 304 stainless steel Type D coupler need later?

Inspect the nitrile gasket each time the coupler is disconnected; replace it at the first sign of cracking, hardening or permanent compression to maintain the 150 psi rating at 70 F.

At what pressure limit does this 1/2 in coupler reach its maximum working rating during sustained use?

The maximum working pressure is 150 psi at 70 F; sustained operation above this pressure or at higher temperatures will exceed the fitting's rated limit first.
