Watts 0959094 Push-to-connect Union Tee 1/2 Inch Od

Product Description

The WATTS 0959094 is a push-to-connect union tee tube fitting designed for quick, tool-free branch connections in plumbing and fluid distribution systems. Molded from polysulfone (PSU), a high-strength engineering thermoplastic, this fitting handles working pressures up to 200 psi. The union tee configuration accepts 1/2 inch OD tubing on all three ports, allowing a single inline connection point to split or merge flow. EPDM o-rings provide a reliable, leak-resistant seal across the tube seats. Licensed plumbers and HVAC technicians install this type of fitting in potable water, compressed air, and hydronic distribution lines where fast service connections are required.

This fitting is suited for residential and light commercial applications where 1/2 inch OD CTS tubing is run for domestic water distribution, filter manifolds, reverse osmosis systems, or similar low-to-medium pressure fluid circuits. The push-to-connect design eliminates soldering, threading, or crimping at the connection point, making it practical for retrofits, repairs, and new installations in tight spaces. It ships individually and can be ordered in single quantities.

Key Features

• Push-to-connect operation requires no tools, solder, or thread compound at the joint
• Rated to 200 psi working pressure
• Polysulfone (PSU) body resists heat, chemicals, and UV degradation
• EPDM o-rings provide durable, watertight seals compatible with potable water service
• Union tee configuration supports inline branch connections on all three 1/2 inch OD ports
• CTS thread type for compatibility with standard copper tube sizing

Compatibility

Designed for use with 1/2 inch OD CTS tubing in push-to-connect plumbing and fluid distribution applications. Verify tubing outside diameter and system pressure rating before installation.

Installation Notes

Installation is performed by licensed plumbers or qualified HVAC technicians. Depressurize and drain the line before inserting or removing tubing from the fitting. Ensure tubing ends are cut square, deburred, and fully inserted to the depth mark before pressurizing. Follow all applicable local plumbing codes and IPC guidelines when installing push-to-connect fittings in potable water systems.
