Malleable Iron Tee for Plumbing Systems

This Zoro Select tee is a Class 150 malleable iron pipe fitting designed for threaded piping installations. It provides a three-way branch connection in residential, commercial or industrial plumbing networks. The FNPT connection type ensures compatibility with standard NPT threads.

Thermals Noise and Pressure Rating

The fitting withstands a maximum pressure of 300 psi at 150 degrees Fahrenheit and a saturated steam pressure of 150 psi. Its temperature range extends from minus 20 degrees to 366 degrees Fahrenheit, suiting hot and cold water distribution. As a passive component it generates no noise and draws no power.

2-1/2 Inch FNPT Connection Size

The pipe size is 2-1/2 inches with female National Pipe Taper threads on all three outlets. Buyers needing a different diameter, a reducing configuration or a socket-weld connection cannot use this fitting. It meets ASME B16.3, B16.4, ASTM A197 and A47 standards and carries FM and UL listings.

Questions about this item

How do I install this 2-1/2 inch FNPT malleable iron tee and what step is often done incorrectly?

Wrap PTFE tape or pipe dope on the male threads only, then tighten each joint two turns past hand-tight with a pipe wrench; the common error is over-tightening female ports which can crack the Class 150 casting.

What maintenance or replacement will this tee need over time?

Inspect threads and the malleable iron body annually for corrosion, leakage or stress cracks; replace the tee if any wall thinning or seepage appears because the material cannot be repaired once the ASTM A197 structure is compromised.

Which limit appears first when this fitting runs at sustained high temperature and pressure?

The saturated steam rating of 150 psi is reached before the 300 psi water rating at 366 °F, so steam service becomes the governing constraint under continuous thermal load.
