Ay Mcdonald 4423-395 Pex-a Poly Insert Tee 1 Inch

Product Description

The AY MCDONALD 4423-395 is a 1-inch PEX-A poly insert tee fitting designed for use in potable water distribution and hydronic piping systems. This tee connects three runs of 1-inch PEX-A tubing using a barbed insert configuration, allowing a branch connection without the need for separate adapters. The poly construction resists corrosion and is compatible with the expansion-style installation methods common in PEX-A systems. Plumbers and pipefitters working on residential and light commercial plumbing installations will find this fitting straightforward to incorporate into new construction or retrofit work.

This fitting is suited for 1-inch PEX-A tubing in water supply and distribution applications, including radiant heating manifold branches, domestic hot and cold water lines, and similar low-pressure piping runs. The insert tee configuration makes it appropriate for use wherever a branch takeoff is required along a main PEX-A line. It is intended for professional installation in systems where PEX-A tubing has already been selected as the pipe material.
