Reliance Worldwide U363LF 1/2 X 1/2 X 3/8 Inch Tee Fitting

Product Description

The RELIANCE WORLDWIDE U363LF is a push-fit tee fitting designed for use in residential and light commercial plumbing systems. It connects two 1/2-inch runs to a 3/8-inch branch line using a tool-free push-to-connect mechanism, eliminating the need for soldering, clamps, or unions at the joint. The fitting accepts copper, CPVC, and PEX tubing, making it a versatile option when working across mixed-material systems. At 0.27 pounds, the U363LF is a compact, lightweight fitting suited for tight spaces in walls, ceilings, and mechanical rooms. Licensed plumbers and knowledgeable installers use this type of fitting for supply line connections and branch takeoffs in potable water systems.

This tee fitting is intended for potable water supply applications in residential and light commercial plumbing. It is commonly installed at branch points where a 3/8-inch feed line splits off from a 1/2-inch main run, such as connections to fixtures, appliances, or ice makers. Its push-fit design allows for quick installation or repair without a torch, making it practical for retrofit and service work in occupied spaces.
