Watts Brass Tubular 3523-10 Quick Connect Tee 1/2 Inch 5 Pack

Product Description

The WATTS BRASS TUBULAR 3523-10 is a 1/2-inch quick connect tee fitting designed for fast, tool-free plumbing connections in residential and light commercial applications. Rated to hold up to 250 psi, this single-piece fitting requires no additional parts to assemble or keep track of during installation. The push-to-connect mechanism allows the installer to simply cut the pipe squarely and push PEX, copper, or CPVC tubing into the fitting end until the tubing seats at the internal stop. The fitting can be disconnected by pulling back on the release ring. It ships in a pack of five units and weighs 0.4 pounds per pack.

The 3523-10 is suited for new construction plumbing and repair work involving PEX, copper, or CPVC pipe. Its code-approved design covers behind-wall installations without access panels and direct in-ground burial, making it a versatile option for rough-in and retrofit scenarios. Licensed plumbers working on residential supply lines will find this fitting applicable wherever a tee branch connection is needed on 1/2-inch lines. It is also cited as a direct replacement for Qest and Flare-It type fittings in existing systems.

Installation Notes

This fitting is installed by licensed plumbers in accordance with applicable IPC and local plumbing codes. Before servicing any supply line, shut off the water supply and relieve system pressure completely. Cut the pipe cleanly and squarely — a ragged or angled cut can prevent proper seating and cause leaks. Do not force tubing beyond the internal stop, and confirm the pipe is fully seated before restoring pressure.
