Watts 0651153 Push-to-connect Brass Tee 1x3/4x1 Inch

Product Description

The WATTS 0651153 is a push-to-connect brass tee fitting designed for tube-to-tube connections in plumbing and fluid distribution systems. The three-port configuration accepts 1-inch OD on two runs and 3/4-inch OD on the branch, allowing directional flow splits or merges without soldering, threading, or compression tools. EPDM O-rings provide a reliable seal against water and common system fluids. The all-brass body offers corrosion resistance suitable for potable water, hydronic, and light commercial distribution lines. Licensed plumbers and pipefitters are the primary installers, though the tool-free connection method puts it within reach of experienced service technicians working on compatible tubing systems.

This fitting is suited for residential and light commercial plumbing, hydronic heating distribution, and water supply branch-off applications where a permanent push-to-connect tee is preferred over soldered or threaded fittings. It is commonly installed at manifold branches, under-sink supply lines, and in-wall or in-ceiling distribution runs where access after installation is limited. The fitting weighs 0.97 pounds and ships as a single unit.

Installation Notes

Installation is performed by a licensed plumber or qualified pipefitter. Shut off the water supply and depressurize the line before inserting or removing tubing from push-to-connect fittings. Ensure tubing ends are cut square, deburred, and free of scoring before insertion to maintain O-ring integrity. Follow all applicable local plumbing codes and IPC guidelines for supply line connections and fitting support spacing.
