Plumbing Reducing Tee 3" x 1-1/4

The Legend Valve 350-237 is a black reducing tee designed for plumbing installations. It connects a 3-inch main line to a 1-1/4-inch branch using female NPT threads on all three ports. This fitting suits contractors and maintenance teams joining dissimilar pipe sizes in water or gas distribution systems.

Pressure Rating and Thread Seal

The SA black finish provides corrosion resistance for standard service conditions. Threaded FNPT connections create a mechanical seal when assembled with appropriate thread sealant or tape. The reducing geometry maintains flow continuity while stepping down the branch diameter without introducing sharp internal transitions.

California Proposition 65 Compliance

This product carries a Proposition 65 warning for chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Installers should follow local safety practices including ventilation and hand protection during assembly. No additional accessories or software are bundled with the fitting.

Questions about this item

How do I install the 3" x 1-1/4" black reducing tee with FNPT threads, and what step is commonly missed?

Apply thread sealant to all three FNPT ends, hand-tighten, then use a pipe wrench for one to two extra turns; the step often skipped is cleaning old sealant from the female threads before reassembly.

What maintenance or replacement will the SA black reducing tee need over time?

Inspect the FNPT joints annually for corrosion or seepage; replace the tee if the cast iron body shows cracking or if threads become stripped during disassembly.

What limit appears first on the 350-237 reducing tee under sustained pressure and temperature cycles?

The cast iron body and FNPT threads reach their pressure-temperature rating before the black coating degrades, so joint leakage at the threads is the first sign of fatigue.
