Parker 164PTC-8 Push-to-connect Union Tee 1/2 in Od Brass

Product Description

The PARKER 164PTC-8 is a push-to-connect union tee tube fitting designed for tube-to-tube connections in air brake and pneumatic plumbing systems. Constructed from brass with a nitrile O-ring seal, it accepts 1/2-inch outside diameter tubing on all three ports. The fitting meets DOT FMVSS 571.106, SAE J2494, SAE J2494-3, and SAE J844 standards, making it a code-compliant choice for commercial vehicle air brake lines. Rated to 250 psi maximum working pressure, it handles a temperature range of -40 degrees F to 200 degrees F. Installation requires no tools on the tube end — tubing seats and locks by hand.

This fitting is used in DOT-regulated air brake systems on commercial vehicles as well as general pneumatic plumbing where push-to-connect tube joints are specified. The union tee configuration allows a branch takeoff without cutting into existing line runs, making it well suited for maintenance, repair, and new installation work on truck, trailer, and fleet vehicle pneumatic circuits. It is sold and installed by licensed commercial vehicle technicians, fleet maintenance shops, and experienced plumbing or pneumatic system installers.

Installation Notes

Installation is performed by qualified commercial vehicle technicians or pneumatic system specialists. Depressurize and drain the air system completely before servicing any fitting. Ensure tubing ends are cut square, deburred, and free of contamination before inserting into the push-to-connect port. Verify the completed joint is leak-tested at system operating pressure before returning the vehicle or system to service.
