Uponor Q4757575 Pex Tee 3/4 Inch Polysulfone

Product Description

The UPONOR Q4757575 is a 3/4-inch PEX tee fitting manufactured from polysulfone, designed for use in domestic potable water distribution systems. This tee creates a branch connection in PEX tubing runs, allowing a single supply line to split into two directions or accepting a branch feed into a main line. Polysulfone is a high-performance thermoplastic chosen for its resistance to high temperatures, chlorine, and the pressures typical in residential and light commercial plumbing. Licensed plumbers and PEX system installers work with this fitting as part of UPONOR ProPEX or compatible expansion-style assemblies.

This fitting is suited for residential and light commercial domestic water applications, including hot and cold supply runs, manifold branch connections, and in-wall or under-slab distribution layouts where PEX tubing is the specified pipe material. It is intended for use in potable water systems and is built to meet the dimensional and material requirements associated with 3/4-inch PEX fitting standards. Its polysulfone construction makes it appropriate for both hot and cold water service lines.

Key Features

• 3/4-inch tee configuration for splitting or branching PEX water lines
• Polysulfone material offers strong resistance to heat, pressure, and chlorinated water
• Designed for domestic potable water distribution systems

Installation Notes

Installation of PEX tee fittings is performed by licensed plumbers in accordance with the International Plumbing Code and local jurisdiction requirements. Shut off and depressurize the water supply before cutting into any existing line. Use the appropriate PEX expansion tool and ring size specified for 3/4-inch connections to ensure a leak-free joint. Do not overtighten or apply thread sealants to expansion-style fittings, as they are not threaded connections.
