Plumbing Multi-Port Tee

The Legend Valve 461-390 is a 3/4 inch closed multi-port tee designed for PEX plumbing installations. It provides eight opposing 1/2 inch outlets to distribute water through a manifold-style layout. The fitting is intended for residential or RV supply systems using expansion connections. Builders handling potable water lines will find it useful for central distribution.

Upgrade From Simple Branching

This tee replaces multiple individual couplings and elbows that would otherwise be required to split a main line into eight branches. The consolidated design reduces the number of connection points and potential leak paths. The jump is worth it when a single supply line must feed numerous fixtures in a compact manifold arrangement. It is not suited for systems that require fewer than eight outlets or a different inlet size.

Sustained Pressure Performance

Constructed from PPSU material compliant with the F1960 standard, the fitting handles continuous pressure and temperature cycles in hot and cold water service. The polymer body resists scaling and corrosion over long service periods. California Proposition 65 warnings indicate the presence of chemicals linked to cancer and reproductive harm. The fitting contains no moving parts, so long-term behaviour depends on the integrity of the expansion joints.

Questions about this item

What size inlet and outlets does the 461-390 multi-port tee use?

The tee has a 3/4 inch closed inlet and eight 1/2 inch opposing outlets for PEX connections.

Which expansion method is required to install the PPSU F1960 PEX ports?

Use a F1960 cold-expansion tool to expand the PEX tubing before seating it on each port; the step often missed is allowing the tube to fully shrink back for a watertight seal.

When should the PPSU multi-port tee be inspected or replaced?

Inspect for stress cracking or discolouration after any system pressure test and replace if the PPSU body shows signs of chemical attack or mechanical damage.
