3 in Coupler with 2 in MNPT Trap

This Banjo 300C cam and groove coupling connects a 3 in hose to a 2 in male NPT thread. The Type C socket accepts a 3 in hose shank and includes a locking arm for secure attachment. Polypropylene body material provides chemical resistance for fluid transfer applications. Maximum working pressure reaches 200 psi at 70 F.

Suits installers joining 3 in hose to 2 in pipe

This coupling fits systems requiring a 3 in hose shank connection on one side and a 2 in male pipe thread on the other. EPDM gasket material handles water and many chemical solutions. Buyers needing a different thread size, hose diameter, or body material such as stainless steel should look at other fittings. The fixed Type C configuration does not adapt to other cam and groove profiles.

Verify hose ID and thread compatibility before

Confirm the existing hose has a 3 in inside diameter to match the coupling shank. Check that the mating port uses 2 in male NPT threads for a proper seal. Ensure system pressure stays within the 200 psi rating at 70 F operating temperature. The polypropylene body and EPDM gasket must be compatible with the fluids being transferred.

Questions about this item

What hose size does the 3 in coupler on the Banjo 300C accept?

The coupler fits a 3 in hose shank with a 3 5/8 in socket inside diameter.

Will the 2 in MNPT thread on the Banjo 300C mate with my existing 2 in female NPT fitting?

Yes, the 2 in MNPT end is cut to standard NPT taper so it threads into any matching 2 in female NPT port.

How can I verify the Banjo 300C is sealed correctly after installation?

Pressurise the line to the 200 psi working pressure at 70 F and check the EPDM gasket for leaks.
