  • PPSU construction resists corrosion and scale buildup in potable water systems
  • Meets ASTM F1960 cold-expansion standard for secure, tool-free connections
  • Multi-port tee design reduces fitting count and potential leak points
  • New condition ensures clean, uncontaminated installation for RV plumbing upgrades

Multi-Port Tee for PEX Systems

This Legend Valve 461-334 fitting connects one-inch and three-quarter-inch supply lines to three half-inch PEX outlets in a single manifold. It is designed for installers building hot or cold water distribution networks in recreational vehicles. The PPSU body meets ASTM F1960 expansion-ring standards for reliable joints.

Replaces Separate Branch Fittings

Using this tee eliminates the need to solder or crimp multiple individual elbows and couplings when splitting a main line into three fixture runs. The consolidation reduces potential leak paths and shortens installation time on tight RV plumbing bays. The jump is worthwhile whenever a single manifold can serve three fixtures instead of discrete fittings.

Sustained Pressure and Temperature Performance

The PPSU material resists scaling and chlorine degradation over years of continuous pressurised service. It maintains structural integrity through repeated thermal cycles between cold inlet and hot water delivery without stress cracking. The expansion-ring connection method creates a permanent seal that does not relax under sustained load.

Questions about this item

What pipe sizes does the 1" x 3/4" x 1/2" multi-port tee connect?

The tee joins a 1 inch main, a 3/4 inch branch and three 1/2 inch outlets for F1960 PEX tubing.

How is the PPSU F1960 tee installed, and what step is often missed?

Use a cold-expansion tool to expand the PEX, insert the fitting, and allow the tube to shrink back; skipping full expansion causes leaks.

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

Check for stress cracks or discolouration after freeze events or if water chemistry changes; replace any fitting that shows damage.
