Uponor Q4751751 Propex Reducing Tee 1x3/4x1 in

Product Description

The UPONOR Q4751751 is a ProPEX reducing tee designed for use in PEX piping systems where a branch line requires a reduced port. This fitting connects 1-inch run ports to a 3/4-inch branch port using the ProPEX expansion connection method. The body is molded from 20 percent glass-reinforced polymer, giving it the strength and temperature resistance required for potable water distribution and hydronic applications. Licensed plumbers and pipefitters install this fitting as part of residential and light commercial water supply systems.

This reducing tee is used in ProPEX PEX-a piping installations where the distribution layout calls for a trunk-and-branch or home-run configuration. The 1 x 3/4 x 1 inch nominal sizing makes it a common choice when dropping a 3/4-inch branch off a 1-inch main line while maintaining full flow continuity through the run. It is suited for domestic water supply, radiant heating distribution manifold branch lines, and similar closed-loop or open plumbing applications where ProPEX fittings are specified.

Key Features

• ProPEX expansion end style for use with PEX-a pipe and an expansion tool
• Nominal sizing: 1 x 3/4 x 1 inch reducing tee configuration
• 20 percent glass-reinforced polymer body for added rigidity and thermal resistance
• Domestic product designation indicating compliance with applicable U.S. sourcing standards
• Reducing branch port allows a 3/4-inch branch off a full 1-inch run without an additional bushing

Compatibility

Designed as an OEM-style ProPEX fitting for use with PEX-a pipe in residential and light commercial plumbing and hydronic systems where ProPEX expansion connections are specified.

Installation Notes

Installation requires an Uponor-compatible ProPEX expansion tool and the correct size PEX rings for each port. Shut off and depressurize the water supply before cutting into any existing line. Work must comply with applicable local plumbing codes, which typically reference IPC or UPC standards for PEX installations. Do not use this fitting with PEX-b or PEX-c pipe, as the ProPEX method is specific to PEX-a tubing.
