Watts 0651150 Push-to-connect Union Tee 3/4x3/4x1/2 Brass

Product Description

The WATTS 0651150 is a push-to-connect union tee fitting designed for tube-to-tube connections in plumbing and fluid distribution systems. Constructed from brass with EPDM O-rings, this fitting joins three tube runs in a tee configuration without the need for soldering, flaring, or threaded assembly. The two run ports accept 3/4 inch OD tubing and the branch port accepts 1/2 inch OD tubing. Licensed plumbers and experienced trades install this fitting in residential and light commercial piping systems where quick, reliable tube connections are required. At 0.7 pounds, it is compact and easy to handle in tight installation spaces.

This fitting is suited for tube-to-tube plumbing applications where three lines converge at a single junction point. Common install scenarios include domestic water distribution, hydronic heating branch circuits, and similar fluid system layouts that use copper or compatible OD tubing. The 3/4 x 3/4 x 1/2 inch OD sizing makes it appropriate for main-run-to-branch transitions where flow is stepped down from a 3/4 inch main to a 1/2 inch branch line. It is packaged and sold individually.

Compatibility

Designed as an OEM-style push-to-connect replacement or new-installation fitting for tube-to-tube plumbing systems using 3/4 inch and 1/2 inch OD tubing.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure before cutting into any existing line. Tubing ends must be cut cleanly and squarely, deburred, and fully inserted to the fitting stop for a proper seal. Do not exceed the fitting rated pressure or temperature limits; consult the manufacturer documentation for operating parameters before installation.
