What this fitting does

The Anvil 0300044401 is a cast iron reducing tee built for Schedule 40 piping systems. It connects a 1 1/2 inch female NPT branch to two 1 inch female NPT outlets in drainage and trap installations. The Class 125 rating confirms it meets standard pressure requirements for residential and light commercial plumbing work.

The spec that decides fit

This tee carries a maximum operating pressure of 175 psi at 150 degrees Fahrenheit. That single figure tells you whether the fitting matches your system design pressure and temperature. If your application exceeds either limit, this component is not suitable and a higher class fitting must be specified.

Capacity and headroom

The reducing tee handles the stated pressure and temperature range for typical drain, waste and vent runs. It runs out of headroom in high pressure hydronic loops, steam lines or any service above 175 psi or 150 degrees Fahrenheit. Buyers needing larger branch sizes or higher pressure classes must select a different fitting.
