Reducing Tee for Piping Systems

This malleable iron reducing tee connects three pipe sections at a 1 inch by 1 inch by 1/2 inch FNPT junction. It is built for plumbers and facility engineers assembling or modifying threaded piping networks in commercial or industrial settings. The Class 150 rating suits standard pressure service.

Thermal and Pressure Performance

The fitting handles saturated steam at 150 psi up to 350 Degrees F and a maximum pressure of 300 psi at 150 Degrees F. Its temperature range spans -20 Degrees to 350 Degrees F, so it remains stable across heating and cooling cycles without degradation. Malleable iron construction resists mechanical shock and vibration in service.

Decisive Specification: 1 in x 1 in x 1/2 in FNPT

The branch size of 1/2 inch on a 1 inch run determines whether this tee matches your piping layout. If the system requires a different branch diameter or a straight coupling, this part will not fit. Verify the exact reduction needed before ordering.

Questions about this item

How do I install the 1 in x 1 in x 1/2 in FNPT reducing tee and what step is often missed?

Wrap PTFE tape clockwise on male threads, hand-tighten, then wrench-tighten one to two turns; the step often missed is checking alignment before final torque to avoid stress on the malleable iron body.

What maintenance or replacement will the Class 150 malleable iron tee need over time?

Inspect threads and seal surfaces annually for corrosion or leakage; replace the fitting if cracks appear or if pressure testing exceeds the 300 psi @ 150 °F rating.

What is the first limit reached under sustained steam use at 350 °F?

The saturated steam pressure limit of 150 psi @ 350 °F is reached before the 300 psi water rating, per ASME B 16.3.
