1/2-inch Schedule 80 coupling

The Banjo CPLG050 is a black polypropylene pipe coupling with FNPT threads on both ends. It suits residential and light-commercial plumbing systems that require a 150 psi pressure rating. Installers use it to join two 1/2-inch male-threaded pipes in drain or trap assemblies.

Hand-tight plus wrench seating

Thread the coupling onto clean male threads by hand until snug, then finish with a strap wrench to avoid cracking the polypropylene. Over-tightening is the most common error and can split the fitting. Use PTFE tape rated for plastic threads; pipe dope may stress the material.

150 psi at 150 °F

The Schedule 80 wall handles the full 150 psi rating up to the 150 °F temperature limit. Above that temperature the pressure capacity drops and the fitting can deform. It is not intended for high-temperature steam lines or pressures beyond the stated maximum.

Questions about this item

How can I verify the 1/2" FNPT coupling is sealing correctly after installation?

Pressurise the line up to the 150 psi rating and check both FNPT threads for leaks; the Schedule 80 polypropylene body should show no weeping at the joints.

What comes with the CPLG050 and what extra parts are needed?

The box contains only the black Schedule 80 polypropylene coupling; you must supply thread sealant or tape and the two 1/2" male NPT pipes or fittings to complete the connection.

When should I choose the 1/2" FNPT Schedule 80 version over other sizes?

Select this coupling when the system runs 1/2" pipe, requires female NPT threads on both ends, and operates between -20 °F and 150 °F at pressures up to 150 psi.
