Reducing Tee for PEX Systems

The Legend Valve 461-937 is a PPSU reducing tee built to the F1960 standard for cold-expansion PEX connections. It joins three different tubing sizes in a single fitting for potable-water distribution in RV and residential plumbing. The polymer body resists corrosion and scale buildup over long service life.

Upgrade from Metal or Push-Fit Tees

This fitting replaces copper sweat tees or push-to-connect models where a tool-free cold-expansion method is preferred. The jump is worth it when the installer wants a permanent, leak-resistant joint without soldering flux or open flame in confined RV compartments. It also eliminates the galvanic-corrosion risk that comes with dissimilar-metal connections.

Install with Cold-Expansion Tool

Installation requires an F1960 expansion tool and matching rings for each tubing diameter. The technician expands the PEX tubing and ring, inserts the tee barb, and allows the tubing to contract for a secure seal. What usually goes wrong is skipping the expansion step or using mismatched ring sizes, which can produce a joint that leaks under pressure. The product carries a California Proposition 65 warning for listed chemicals.

Questions about this item

What pipe sizes does the 1-1/4" x 1" x 3/4" tee connect?

The tee joins 1-1/4 inch, 1 inch and 3/4 inch PEX tubing using F1960 expansion fittings.

Which expansion tool standard is required for the F1960 connections?

Use an F1960-compliant expansion tool and matching rings; the step often missed is fully expanding the pipe before inserting the fitting.

When should the PPSU tee be inspected or replaced?
