Uponor Q2227557 Flow-through Tee 3/4 in Propex Polysulfone

Product Description

The UPONOR Q2227557 is a 3/4-inch flow-through tee fitting designed for use with ProPEX expansion-style PEX tubing systems. Constructed from polysulfone, this tee maintains full flow through the run while providing a branch takeoff, making it a core component in residential and light commercial plumbing distribution manifolds and branch runs. The ProPEX connection method requires an expansion tool and PEX ring, creating a reliable, leak-resistant joint. Licensed plumbers and PEX-certified installers working on domestic water systems are the primary users of this fitting.

This tee is suited for domestic potable water applications where ProPEX fittings are specified. It is commonly installed in residential new construction and remodel projects where PEX tubing is run from a main trunk line to individual fixtures or zones. The flow-through design keeps pressure drop low across the run leg, which is an advantage in trunk-and-branch plumbing layouts.

Key Features

• 3/4-inch ProPEX connection on all ports for use with standard PEX expansion tooling
• Polysulfone construction offers high-temperature and chemical resistance suitable for domestic water service
• Flow-through tee design minimizes pressure drop across the run leg

Compatibility

Designed as an OEM-style ProPEX fitting for use in residential and light commercial domestic potable water plumbing systems utilizing 3/4-inch PEX tubing with the ProPEX expansion connection method.

Installation Notes

Installation requires a calibrated ProPEX expansion tool and correctly sized PEX rings. Licensed plumbers should follow all applicable local plumbing codes and IPC guidelines for potable water system installations. Shut off the water supply and depressurize the line before cutting into an existing system. Allow the expanded fitting connection to recover fully before pressurizing the line.
