1-1/2" x 1-1/4" FNPT 304 SS Reducing Coupling

This ZORO SELECT reducing coupling connects 1-1/2 inch and 1-1/4 inch female NPT threaded pipes. It is manufactured from 304 stainless steel for corrosion resistance. The fitting features a straight design rated for Schedule 40 pipe and Class 150 service. It handles a maximum operating pressure of 300 psi.

Plumbers joining dissimilar NPT pipe sizes

This coupling suits installers needing a straight transition between 1-1/2 inch and 1-1/4 inch female threaded connections in stainless steel systems. It is not for applications requiring a different material grade, higher pressure rating, or alternative thread standard such as BSPT. Buyers needing a coupling for identical pipe sizes should select a straight coupling instead.

Verify thread size and pressure rating before

Confirm that both pipe ends match the 11.5 threads per inch NPT specification listed for each port. Ensure the system operating pressure does not exceed the 300 psi maximum rating. Check that Schedule 40 pipe dimensions align with the coupling design for proper engagement.

Questions about this item

What pipe threads must I already have to connect this 1-1/2" FNPT reducing coupling?

You need one pipe with 1-1/2" FNPT threads at 11.5 threads per inch and another with 1-1/4" FNPT threads at the same 11.5 TPI pitch.

Will this Class 150 stainless coupling handle the pressure from my existing Schedule 40 system?

Yes, the coupling is rated for 300 psi maximum operating pressure and is designed for Schedule 40 piping, matching typical Class 150 service conditions.

How can I verify the 304 stainless coupling is sealing properly after installation?

Pressurise the line up to the 300 psi rating and check both threaded joints for leaks; a dry, drip-free connection at test pressure confirms correct assembly.
