Anvil 359 Class 125 Reducing Tee for Drainage

This Anvil 359 Class 125 reducing tee connects three female NPT pipes in a drainage network. The cast iron body handles 175 psi at 150 degrees F and suits Schedule 40 piping. It fits residential and commercial waste lines where a 1-inch branch joins two 1-1/4-inch runs.

Straightforward NPT Threaded Installation

The three female NPT ports accept standard pipe threads without soldering or adhesives. Apply thread sealant rated for cast iron and tighten to specification to avoid cracking the brittle material. Misaligned pipes or over-torqued joints are the usual causes of leaks on this fitting.

Questions about this item

How can I confirm the reducing tee is seated correctly after installation?

Check that all three NPT female threads engage fully without cross-threading, then pressure-test the joint up to 175 psi at temperatures not exceeding 150 °F to verify a leak-free seal.

What comes with the Anvil 0300039609 reducing tee and what must I supply?

The box contains only the Class 125 cast-iron tee with 1-1/4", 1-1/4" and 1" NPT female openings; you must provide Schedule 40 pipe, thread sealant or tape, and appropriate wrenches for assembly.
