The RWC UC412LFA10 is a 10-pack of SharkBite brass PEX barb reducing tees sized 3/4 inch x 3/4 inch x 1/2 inch. Each fitting allows in-line pipe-size reduction at the branch outlet, making it a practical choice when transitioning from a 3/4-inch main run to a 1/2-inch branch line. The barb design is compatible with both stainless steel clamp ring systems and copper crimp ring systems, giving installers flexibility on the jobsite. Clamp and crimp tools are sold separately. These fittings are lead-free brass and carry NSF/ANSI 61 and NSF 372 certifications, making them approved for potable water contact.
These reducing tees are suited for residential and light commercial potable water distribution systems as well as hydronic heating applications. A typical install scenario involves teeing off a 3/4-inch PEX main to feed a 1/2-inch branch to a fixture or zone. The 10-pack format is useful for rough-in work where multiple tee connections are needed in a single project, reducing trips to the supply house.
Compatible with PEX tubing in potable water distribution and hydronic heating systems using stainless steel clamp ring or copper crimp ring installation methods per ASTM F1807.
Installation is performed by licensed plumbers following applicable IPC and local plumbing code requirements. Shut off the water supply and depressurize the line before cutting into existing piping. Use a calibrated clamp or crimp tool appropriate to the ring type and tubing size to ensure a leak-free connection. Inspect each barb seat and tubing end for burrs or debris before assembly.
