Uponor Q4751533 Reducing Tee 1-1/2x1-1/4x1-1/4 Propex

Product Description

The UPONOR Q4751533 is a reducing tee fitting designed for use in ProPEX expansion-style plumbing systems. It connects runs of differing pipe sizes, transitioning from a 1-1/2-inch nominal main run down to 1-1/4-inch nominal branch and outlet connections. The fitting is molded from modified polyphenylsulfone, a high-performance thermoplastic that resists elevated temperatures and the stresses common in hydronic and potable water distribution. Licensed plumbers and pipefitters install this fitting during rough-in or system modification work where a reducing branch connection is required.

This reducing tee is suited for residential and light commercial plumbing systems that use ProPEX end connections. Typical applications include hydronic heating distribution, domestic hot and cold water supply, and radiant panel supply and return piping. The ProPEX end style requires an expansion tool and PEX expansion rings to make connections, which is standard procedure in systems using Uponor PEX-a pipe. The domestic designation indicates this fitting is manufactured in the United States.

Key Features

• Reducing configuration: 1-1/2 inches nominal main run, 1-1/4 inches nominal branch and outlet
• ProPEX end style for use with PEX-a expansion tooling and expansion rings
• Molded from modified polyphenylsulfone for high-temperature and pressure resistance
• Domestic manufacture
• Enables branch connections in multi-zone or multi-size distribution systems

Compatibility

Designed for use in ProPEX expansion-style PEX-a plumbing and hydronic systems requiring a reducing tee at 1-1/2 x 1-1/4 x 1-1/4 inch nominal pipe sizes.

Installation Notes

Installation requires a calibrated ProPEX expansion tool and correctly sized PEX expansion rings for each connection port. Shut off water supply and depressurize the system before cutting into existing pipe. Follow all applicable local plumbing codes and ASTM F1960 expansion connection standards. Allow expansion joints to recover fully before pressurizing the system.
