Heatlink 16255 Pex Tee Fitting 3/4 X 1/2 X 1/2

Product Description

The HEATLINK 16255 is a PEX tee fitting designed for use in hydronic heating, potable water distribution, and radiant floor systems. This tee provides a branch connection in a run of PEX tubing, with a 3/4-inch run on the main line and 1/2-inch outlets on the branch and the opposing run end. The 3/4 x 1/2 x 1/2 configuration makes it well suited for transitioning from a larger supply main down to smaller branch lines. Plumbers and hydronic system installers use this fitting to build out distribution manifolds, stub-off runs, and zone piping in both residential and light commercial applications.

This fitting is appropriate for residential hot and cold water supply systems, in-floor radiant heating loops, and baseboard hydronic distribution where PEX tubing is the primary pipe material. The reducing tee configuration is commonly installed at branch points where the main supply line is 3/4 inch and individual zone or fixture drops require 1/2-inch tubing. It is sold as a single unit, allowing installers to purchase exactly the quantity needed for the job.

Key Features

• 3/4 x 1/2 x 1/2 reducing tee configuration for transitioning between PEX line sizes
• Compatible with standard PEX expansion or crimp installation methods appropriate to fitting design
• Single-unit selling format for precise quantity ordering
• Suitable for hydronic heating and potable water distribution in PEX systems

Compatibility

Designed as an OEM-style replacement or new-installation fitting for residential and light commercial PEX piping systems using 3/4-inch and 1/2-inch PEX tubing.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable IPC or local plumbing code requirements. Shut off the water supply and depressurize the line before cutting into existing PEX runs. Use the appropriate PEX crimp, clamp, or expansion tool rated for the fitting type to ensure a leak-free connection. Inspect the connection for proper seating before restoring system pressure.
