Pro-source PC64-DOT-4 Brass Union Tee Push-to-connect 1/4in

Product Description

The PRO-SOURCE PC64-DOT-4 is a brass union tee fitting with a push-to-connect design built for general-purpose tubing systems. It accepts 1/4-inch outside diameter tubing and meets DOT standards, making it suitable for fluid and air line applications where a reliable, tool-free branch connection is required. The brass construction provides corrosion resistance and mechanical durability in both stationary and mobile equipment environments. Plumbers, HVAC technicians, and fluid-systems installers use this fitting to create a three-way branch in a tubing run without threaded fittings or compression tools.

This union tee is intended for general-purpose applications involving 1/4-inch OD tubing. Its DOT-compliant construction makes it appropriate for use in pneumatic lines, fluid transfer systems, and similar light-to-medium-duty service scenarios found in both commercial and residential installations. The push-to-connect interface allows for quick field assembly, which is useful during service calls or system modifications where downtime needs to be minimized.

Key Features

Compatibility

Designed for general-purpose use with 1/4-inch OD tubing in pneumatic and fluid transfer systems where DOT-standard fittings are specified.

Installation Notes

Installation is performed by trade professionals including plumbers and HVAC technicians. Shut off all pressure to the line and verify the system is fully depressurized before inserting or removing tubing. Ensure tubing ends are cut cleanly and squarely and are free of burrs before inserting into the fitting to maintain a proper seal. Follow all applicable codes and the equipment manufacturer guidelines for pressure ratings and tube compatibility.
