4" Cam Lever Coupling Adapter

The Banjo 400A is a Type A cam and groove adapter with a 4-inch male adapter and FNPT thread. It connects hoses or piping in fluid-transfer systems using a cam lever locking mechanism. The body is moulded from HAWA polypropylene for chemical resistance. A 4 3/4-inch plug diameter and 4 1/2-inch overall length suit standard 4-inch couplings.

Suits industrial fluid handling.

This adapter suits agricultural, industrial and chemical-transfer lines operating at or below its rated pressure. The EPDM gasket handles water, fertiliser and many mild chemicals. Buyers needing higher working pressures, metal bodies or different thread standards should select alternative fittings. The locking arm is not included with this model.

Rated to 75 psi at 70°F

At 70°F the coupling holds a maximum working pressure of 75 psi. Polypropylene construction provides good chemical compatibility and light weight. Above the rated temperature or pressure the material strength drops and the seal may fail. The 2 3/8-inch plug length allows full engagement in standard cam sockets.

Questions about this item

What size NPT thread must the existing pipe or fitting have to accept the 400A adapter?

The adapter connects to a 4-inch NPT female thread, so the mating component must provide a matching 4-inch male NPT end.

Will the polypropylene body and EPDM gasket hold up when paired with older metal cam-lever fittings?

Yes, the 4-inch cam groove on the adapter follows the standard Type A profile, so it locks securely onto legacy metal couplers of the same size.

How can I confirm the joint is sealed to the rated 75 psi at 70 °F after assembly?

Pressurise the line to the working pressure and check for leaks at the cam arms and the NPT threads; no weeping means the EPDM gasket and thread seal are functioning.
