Anvil 1-1/2" Reducing Tee

The Anvil 0310045604 is a malleable iron reducing tee designed for plumbing drain and trap installations. It connects three female NPT threads at 1-1/2 inch, 1-1/2 inch, and 1 inch sizes. This Class 150 fitting suits Schedule 40 pipe systems in residential or commercial applications.

Replaces damaged or undersized tees

Upgrade when an existing tee shows corrosion, leaks, or cannot accommodate a required branch size reduction. The jump is worth it when system pressure demands a 300 psi rating at 150 degrees Fahrenheit and a durable iron construction is preferred over plastic alternatives.

Limited to threaded NPT connections

The fitting requires male NPT threads on all three connecting pipes for a sealed joint. It cannot join plain-end, solvent-weld, or press-fit piping without appropriate adapters. The Class 150 pressure class restricts use to services within the rated 300 psi operating limit.

Questions about this item

Will the 1-1/2" female NPT ends match Schedule 40 pipe threads?

Yes, the tee is rated for Pipe Schedule 40 and uses standard NPT threads on all three ports, so it threads directly onto matching Schedule 40 pipe nipples.

Do I need to apply thread sealant on the NPT connections during installation?

Apply PTFE tape or pipe dope to the male threads before tightening; the tapered NPT seal relies on that compound to prevent leaks at the 300 psi rating.

How often should I inspect the malleable iron body for corrosion?

Check the black iron surfaces annually for rust or scale, especially if the system carries condensate or sees temperature cycles near the 150 °F limit.
