Coupler for 1" NPT lines

The Banjo 125B is a Type B cam-and-groove socket built from polypropylene with an EPDM gasket. It accepts a 1" male NPT thread on one side and a 1-1/4" hose fitting on the other, making it suitable for fluid-transfer assemblies in agricultural or industrial plumbing. The coupler has an overall length of 3-1/8" and a socket inside diameter of 1-1/2".

Verify thread and hose compatibility

Before ordering, confirm that the mating component carries a 1" male NPT thread and that the hose or tube end measures 1-1/4" for the cam-groove connection. The locking arm is not included, so a separate arm or pin must be sourced if the installation requires a secured coupling. Check that the polypropylene body and EPDM seal are compatible with the fluids and temperatures in your system.

Pressure rating at sustained temperature

The coupling is rated for a maximum working pressure of 300 psi at 70 °F. Under sustained load at this temperature the polypropylene body and EPDM gasket maintain their seal without the creep that can appear during short pressure spikes. Performance at higher temperatures will be lower, so plan the system pressure accordingly.

Questions about this item

Does the 125B include a gasket or do I need to buy an EPDM gasket separately?

The coupling comes with an EPDM gasket already fitted, so no separate gasket purchase is required.

Should I choose the 125B or a different model for a 1 1/4 inch MNPT connection?

The 125B is built for a 1 1/4 inch MNPT thread, matching that exact connection size.

What does the 300 psi rating at 70 F mean when the coupling is installed?

It indicates the maximum working pressure the polypropylene body can handle at that temperature in service.
