Uponor LF4701010 Propex Brass Tee 1 Inch

Product Description

The UPONOR LF4701010 is a 1-inch ProPEX brass tee fitting designed for use in PEX plumbing distribution systems. This lead-free brass fitting connects three runs of 1-inch PEX tubing in a standard tee configuration, allowing branch takeoffs in hot and cold water supply lines. The ProPEX connection method requires an expansion tool and ProPEX rings to create a secure, leak-resistant joint. Licensed plumbers and pipefitters install this fitting during new construction and remodel work on residential and light commercial water distribution systems.

This tee fitting is suited for potable water supply applications where a branch connection is needed in a 1-inch PEX line. The ProPEX expansion-style connection is common in residential water distribution, radiant heating supply lines, and manifold branch piping. Its lead-free brass construction meets requirements for use in drinking water systems under applicable plumbing codes.

Key Features

• 1-inch ProPEX connection on all three ports for consistent sizing throughout the tee
• Lead-free brass construction suitable for potable water service
• Expansion-style ProPEX joint resists pullout and accommodates pipe movement
• Compatible with standard ProPEX expansion rings and tooling
• Applicable for both hot and cold water supply lines

Compatibility

Designed as an OEM-style ProPEX fitting for use with 1-inch PEX tubing in residential and light commercial plumbing systems where ProPEX expansion connections are specified.

Installation Notes

Installation requires a calibrated ProPEX expansion tool and appropriately sized ProPEX rings. Shut off the water supply and depressurize the line before making any connections. Work must comply with local plumbing codes, including IPC and applicable state amendments governing PEX systems. Allow expanded connections to contract fully before pressurizing the system.
