Anvil Reducing Tee 1-1/4" x 1" x 1" FNPT

This Anvil reducing tee connects three pipe sections using Female NPT threads. The fitting accepts one 1-1/4 inch pipe and two 1 inch pipes in a tee configuration. It is made from malleable iron and rated for Schedule 40 piping systems. Plumbers and maintenance teams use it to branch or reduce pipe runs in commercial and residential installations.

Class 150 pressure rating and 300 psi maximum

The fitting carries a Class 150 designation with a maximum operating pressure of 300 psi at 150 degrees Fahrenheit. Malleable iron construction provides mechanical strength for typical water, oil, or gas distribution at these pressures. No moving parts or seals generate noise, and the material does not consume power. Thermal expansion follows standard iron behaviour within the rated temperature range.

Sustained pressure hold at rated temperature

Under continuous operation at 300 psi and 150 degrees Fahrenheit, the tee maintains its seal without degradation. The malleable iron body resists creep and fatigue across the full Class 150 service envelope. No performance drop-off occurs during extended duty cycles compared with short-term pressure tests. The fitting remains within specification for the duration of its installed service life.

Questions about this item

How do I install the Anvil 310043401 reducing tee and which step is commonly missed?

Thread the three FNPT ends onto Schedule 40 pipe using pipe sealant on male threads, tightening to the Class 150 pressure rating; the step often missed is confirming all three ports are 1 in or 1-1/4 in FNPT before assembly.

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

Inspect threads and the HAWA iron body periodically for corrosion or leakage at 300 psi operating pressure; replace the fitting if cracks appear or if sealant degrades after repeated thermal cycles to 150 Degrees F.

What is the first limit reached under sustained use at maximum pressure and temperature?

The 300 psi @ 150 Degrees F Class 150 rating is the primary limit; sustained operation at that pressure and temperature will stress the malleable iron and thread sealant before any other factor.
