Anvil 1" x 1/2" FNPT Galvanized Reducer

This galvanized malleable iron reducing coupling connects 1 inch and 1/2 inch female NPT pipe threads. Rated for Class 150 service on Schedule 40 pipe, it handles water, air or oil lines in residential and light commercial plumbing. The Standard Domestic casting meets common code requirements for potable and non-potable systems.

300 psi at 150 °F pressure rating

The fitting holds up to 300 psi at 150 °F, giving ample headroom for typical supply pressures and hot-water loops. It is not suited for steam service above the rated temperature or for systems that exceed the Class 150 pressure envelope. Buyers needing higher pressure classes or larger diameter transitions should select a different fitting.

Questions about this item

Will the 1" x 1/2" FNPT threads on this galvanized reducer match the NPT threads on my existing Schedule 40 iron pipe?

Yes, both ends use Female NPT threads designed for Schedule 40 pipe, so the 1" and 1/2" connections will engage your existing pipe threads directly.

How can I confirm the coupling is holding pressure correctly after I install it?

Pressurise the system up to the 300 psi rating at temperatures not exceeding 150 °F and inspect both the 1" and 1/2" FNPT joints for any sign of leakage.
