Value Brand Reducer Coupling 1-1/4" x 3/4" FNPT

This malleable iron reducer coupling connects a 1-1/4 inch female NPT pipe to a 3/4 inch female NPT pipe. It is rated for Class 150 service in standard plumbing installations. The fitting is new and supplied by ZORO SELECT for general purpose use.

Class 150 Pressure Rating

The Class 150 designation defines the maximum working pressure this coupling can safely contain. Systems operating above this class rating require a higher-rated fitting to avoid failure. Verify the system pressure before installation to ensure compatibility.

1-1/4" to 3/4" Pipe Reduction

This coupling joins pipes with a 1-1/4 inch and a 3/4 inch nominal bore using female NPT threads. It does not suit connections requiring male threads, compression ends, or larger diameter step-downs. Installers needing different thread types or size transitions must select an alternative fitting.

Questions about this item

What does the Class 150 rating mean for pressure handling in a real installation?

Class 150 indicates the maximum working pressure the malleable iron body is rated for under standard conditions, so the coupling will hold up to that limit in a properly assembled pipe system.

How does the NPT thread standard affect the seal on this reducer?

Both ends use Female NPT threads — 11-1/2 threads per inch on the 1-1/4 inch side and 14 threads per inch on the 3/4 inch side — so sealing relies on taper engagement and thread sealant or tape.

What clearance and alignment are needed to fit this coupling between the two pipe sizes?

The malleable iron body connects a 1-1/4 inch female NPT pipe to a 3/4 inch female NPT pipe, so you need enough straight run on each pipe to engage the full thread depth and space for a wrench on the coupling flats.
