Reducer Coupling 1-1/2 × 1-1/4 in

This Anvil malleable-iron reducer coupling connects a 1-1/2 inch FNPT pipe to a 1-1/4 inch FNPT pipe. It is rated Class 150 with a maximum working pressure of 300 psi at 150 °F and handles saturated steam up to 150 psi. The fitting operates from -20 °F to 350 °F and meets ASME B16.3 standards.

Plumbing installers and maintenance crews

The coupling suits installers joining dissimilar pipe sizes in water, oil, air or saturated-steam systems that stay within the stated pressure and temperature envelope. It is not for lines that exceed 300 psi at 150 °F, for super-heated steam service, or for applications requiring welded rather than threaded joints.

Class 150 pressure rating

The single specification that decides fit is the Class 150 rating, which sets the 300 psi at 150 °F limit and the 150 psi saturated-steam limit. Verify that your system design pressure and temperature fall inside these boundaries before selecting this reducer coupling.

Questions about this item

How do I install the 1 1/2 in x 1 1/4 in FNPT reducer coupling without leaking?

Clean both male threads, apply PTFE tape or pipe dope clockwise on the external threads only, thread the coupling on by hand until snug, then tighten one to two turns with a wrench; the step most people miss is skipping the thread sealant, which causes leaks at the Class 150 joint.

What maintenance or replacement will this malleable iron coupling need over time?

Inspect the FNPT threads and sealing surfaces annually for corrosion, mineral buildup, or cracking; replace the coupling if you see visible rust pitting, deformed threads, or any weeping at the joint, as the malleable iron body itself does not have serviceable internal parts.

What is the first limit I will hit if I run saturated steam through this fitting continuously?

The saturated steam rating of 150 psi is the first limit reached under sustained steam service; the fitting is also rated 300 psi at 150 °F and a maximum temperature of 350 °F per ASME B16.3, but steam pressure must not exceed 150 psi.
