Uponor Q4752275 Reducing Tee 2x2x3/4 in Propex Ppsu

Product Description

The UPONOR Q4752275 is a reducing tee fitting designed for use in ProPEX expansion-style piping systems. It connects two 2-inch run ports with a 3/4-inch branch outlet, allowing distribution lines to tap off a main trunk without reducing flow capacity on the primary run. The fitting is molded from polyphenylsulfone (PPSU), a high-performance thermoplastic known for its resistance to elevated temperatures, chlorinated water, and mechanical stress. Licensed plumbers and hydronic system installers use this fitting in potable water distribution, radiant heating, and commercial plumbing rough-in applications where reliable, long-term joint integrity is required.

This reducing tee is suited for residential and light commercial ProPEX installations where a 2-inch main line branches to a 3/4-inch secondary line. Typical applications include domestic hot and cold water distribution manifolds, branch takeoffs in multi-family plumbing systems, and hydronic heating supply and return piping. It is manufactured domestically and is compatible with the ProPEX expansion connection method, which requires an expansion tool and ProPEX rings to form a secure, memory-fit joint at each port.

Key Features

• Reducing configuration: 2 x 2 x 3/4 inches nominal for main-run-to-branch transitions
• ProPEX end style requires expansion tool and ProPEX rings for installation
• Polyphenylsulfone (PPSU) construction offers high temperature and chemical resistance
• Domestically manufactured fitting
• Suitable for potable water, radiant heating, and hydronic piping systems

Compatibility

Designed for use with ProPEX expansion-style PEX piping systems. Compatible with 2-inch and 3/4-inch ProPEX rings and PEX-a tubing at the corresponding ports. No specific model compatibility data was provided beyond the ProPEX end style and nominal sizing stated above.

Installation Notes

Installation must be performed by a licensed plumber following applicable local plumbing codes and IPC requirements. Shut off the water supply and relieve system pressure completely before making any connections. A calibrated ProPEX expansion tool is required to expand PEX-a tubing and ProPEX rings at each port — do not attempt to install without the correct expansion tooling, as under-expanded joints will leak. Allow joints to recover fully before pressurizing the system.
