3" Polypropylene Cam Lever Coupling

The Banjo 300B is a Type B cam and groove coupling with a 3-inch female socket and a 3-inch male NPT thread. It is built from HAWA polypropylene with an EPDM gasket for chemical compatibility. The coupling is rated for a maximum working pressure of 150 psi at 70 degrees Fahrenheit. Plumbers and maintenance crews use it for quick, tool-free hose connections in fluid-transfer systems.

Cam Lever Without Locking Arm

The design relies on the cam lever alone to secure the connection; no locking arm is included in the assembly. This allows rapid make-and-break cycles when frequent line changes are required. The EPDM gasket provides the seal between the socket and the mating adapter. Users must verify that the lever engagement is sufficient for their specific pressure and vibration conditions.

3-Inch Flow Path With 150 PSI Rating

The socket inside diameter measures 3 5/8 inches and the overall length is 3 13/16 inches, giving an unobstructed 3-inch flow path. The 150 psi pressure rating at 70 degrees Fahrenheit defines the safe operating envelope for water and compatible chemicals. The coupling is not suited for applications exceeding this pressure or for fluids that attack polypropylene or EPDM. Installers needing higher pressure ratings or different seal materials must select an alternative fitting.

Questions about this item

How often should the EPDM gasket be inspected or replaced on this 300B coupler?

Inspect the EPDM gasket each season and replace it if you see cracks, hardening or flattening that prevents a tight seal.

At what pressure does the polypropylene body reach its rated limit during continuous operation?

The maximum working pressure is 150 psi at 70 °F; sustained use above that level can deform the body.

Does the polypropylene body soften or leak when the fluid temperature stays above 70 °F all day?

Above 70 °F the 150 psi rating drops, so prolonged hot service requires lower pressure to avoid creep or seal failure.
