Sioux Chief 672WP0390 Pex-a Multiport Tee 3/4 in 3-port

Product Description

The SIOUX CHIEF 672WP0390 is a 3/4-inch F1960 PEX-A polypropylene multiport tee fitting with three ports closed. This fitting connects to F1960 PEX-A expansion-style pipe using the cold-expansion method, creating a secure, reliable joint suited for potable water distribution and hydronic systems. The closed-port design allows unused branch connections to remain sealed during initial installation or future system modifications. Licensed plumbers and pipefitters install this fitting as part of residential and light commercial PEX manifold or branch-line layouts.

This multiport tee is intended for use in PEX-A water supply systems following the F1960 expansion fitting standard. It fits cleanly into manifold-style plumbing configurations where a single trunk line needs to branch into multiple supply runs. The closed ports allow the installer to open only the connections needed at the time of roughin, keeping unused ports sealed and the system pressure-tight. Typical applications include new residential construction, remodel work, and radiant heating distribution layouts where PEX-A tubing is specified.

Key Features

• F1960 PEX-A expansion-style connection — no crimp rings or clamps required
• 3/4-inch size fits standard residential PEX-A trunk and branch lines
• Three-port closed design keeps unused branch ports sealed from the factory
• Polypropylene construction resists corrosion and scale buildup
• Multiport layout reduces the number of individual fittings needed at a manifold location

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 3/4-inch F1960 PEX-A expansion-style plumbing systems.

Installation Notes

Installation requires a PEX-A expansion tool sized for 3/4-inch F1960 fittings. Shut off the water supply and depressurize the line before cutting into any existing system. Work must comply with local plumbing codes and applicable IPC or UPC requirements. Allow the expanded pipe end to recover fully onto the fitting before pressurizing the system.
