1/2 in Cam & Groove Coupling

This USA INDUSTRIALS fitting is a Type C cam and groove coupling with a 1/2 in hose shank connection. The body is constructed from 304 stainless steel for corrosion resistance. It includes a nitrile gasket and does not feature a locking arm. The socket inside diameter measures 15/16 in.

Replaces worn hose shank fittings

Use this coupling to replace a damaged or leaking cam and groove socket on 1/2 in hose assemblies. The upgrade is worth it when the existing fitting shows corrosion, stripped cam arms or a hardened gasket that no longer seals at 150 psi. A new 304 stainless body restores pressure integrity and chemical compatibility.

Verify hose ID and pressure rating

Confirm the hose inside diameter is exactly 1/2 in to match the shank size. Ensure the system operating pressure does not exceed the 150 psi maximum working pressure at 70 F. Check that nitrile gasket material is suitable for the fluid being transferred. The overall length is 72.2 mm for installation spacing.

Questions about this item

Will the 15/16 in socket inside diameter fit my 1/2 in hose?

The coupling is sized for a 1/2 in hose I.D. and the socket inside diameter is 15/16 in, so the hose shank inserts fully before the cam arms close.

What is the correct way to lock the cam arms on this Type C coupler?

Insert the male adapter until it seats against the gasket, then press both cam arms down firmly until they latch; the arms must be fully closed to seal at 150 psi.

When should the nitrile gasket be replaced?

Replace the nitrile gasket if you see cracks, flattening, or if the coupling weeps at the rated 150 psi working pressure.
