Reducing Coupling 3" x 2" Schedule 80

The Banjo RC300-200 is a black polypropylene reducing coupling with FNPT x FNPT connections. It joins a 3-inch female thread to a 2-inch female thread in drainage or fluid-transfer systems. The Schedule 80 rating supports a maximum pressure of 150 psi across a temperature range of -20 to 150 degrees Fahrenheit.

Suits high-pressure drainage and chemical lines

Installers needing a Schedule 80 polypropylene transition between 3-inch and 2-inch FNPT threads will find this coupling matches the required pressure and temperature limits. It is not for systems that demand a different thread standard, a larger size step, or a material other than polypropylene.

Schedule 80 pressure rating decides fit

The 150 psi maximum pressure at 150 degrees Fahrenheit is the single specification that determines whether this coupling meets the design conditions of the piping system. Verify the operating pressure and temperature against these limits before selection.

Questions about this item

What pipe sizes does the 3 in x 2 in Schedule 80 reducing coupling connect?

This Banjo RC300-200 coupling joins a 3 inch female NPT thread to a 2 inch female NPT thread, both Schedule 80 polypropylene.

How do I install the FNPT x FNPT reducing coupling without leaking?

Wrap PTFE tape clockwise on the male threads, hand-tighten into each FNPT end, then finish with one to two turns using a strap wrench — overtightening cracks the polypropylene.

When should I replace the black polypropylene coupling in a chemical drain line?

Replace it if you see stress cracks, thread deformation, or if the line exceeds the 150 psi rating or the -20 °F to 150 °F temperature range.
