Uponor Q4751515 Pex Tee Fitting 1-1/2 Inch

Product Description

The UPONOR Q4751515 is a 1-1/2 inch PEX tee fitting manufactured from modified polyphenylsulfone (PPSU), a high-performance thermoplastic known for its durability and resistance to high temperatures and chlorinated water. This tee is designed for use in PEX piping systems, allowing a branch connection at a 90-degree angle to the main run. It is installed by licensed plumbers and pipefitters in residential and light commercial hydronic and domestic water distribution applications. The PPSU construction makes it well suited for hot and cold potable water systems where long-term chemical and thermal performance is required.

This fitting is used in PEX expansion-style plumbing systems, where the fitting sleeve is expanded and the PEX tubing is inserted before the sleeve contracts around the connection. Typical applications include domestic hot and cold water supply lines, in-floor radiant heating distribution, and manifold branch runouts. The domestic designation indicates the product is manufactured for the North American market and meets applicable potable water standards.
