Sharkbite UC454LFA Brass Barb Reducing Pex Tee

Product Description

The SHARKBITE UC454LFA is a brass barb reducing PEX tee fitting used to join PEX tubing in residential and light commercial plumbing systems. The reducing configuration allows a single fitting to connect two different tube sizes at one junction, eliminating the need for an additional reducing coupling in the run. Constructed from brass, the fitting provides corrosion resistance and durability in potable water applications. Licensed plumbers and experienced DIYers install this fitting by hand without specialized crimping tools, inserting the barbed ends directly into compatible PEX tubing.

This fitting is suited for residential water distribution systems, radiant heating loops, and retrofit plumbing projects where PEX tubing is the pipe material of choice. The reducing tee design is particularly useful when branching from a main supply line to a smaller branch line, a common scenario in manifold-free zoned plumbing layouts and fixture supply runs.

Key Features

• Brass construction provides corrosion resistance for potable water service
• Barb-style ends allow tool-free push-in installation onto PEX tubing
• Reducing tee geometry connects two tube sizes at a single junction
• Sold individually, allowing precise quantity purchasing for each job

Compatibility

Designed as an OEM-style replacement and new-installation fitting for residential and light commercial PEX plumbing systems using barb-connection PEX tubing.

Installation Notes

Installation is performed by licensed plumbers or qualified individuals in accordance with local plumbing codes and the IPC. Shut off the water supply and depressurize the line before cutting into existing piping. Ensure cut tube ends are clean, square, and free of burrs before seating onto the barbs. Where required by code, secure barb connections with approved clamps or crimp rings using the appropriate tool.
