Parker 165PTC-5/32 Push-to-connect Tube Fitting

Product Description

The PARKER 165PTC-5/32 is a push-to-connect tube-to-tube fitting designed for fast, tool-free connections in compressed air and fluid line applications. Constructed from brass with a nitrile O-ring, it accepts 5/32-inch OD tubing and is rated for a maximum working pressure of 250 psi. The fitting is D.O.T. compliant for air brake service, making it suitable for commercial vehicle and heavy-duty pneumatic systems. Plumbers, HVAC technicians, and fleet maintenance professionals install this type of fitting where reliable, leak-free tube connections are required without the need for compression sleeves or ferrules.

This fitting is suited for pneumatic control lines, air brake circuits, and fluid transfer tubing in both mobile and stationary equipment. Its operating temperature range of -40 degrees F to 200 degrees F covers most ambient and under-hood environments. The push-to-connect design allows quick installation and, depending on system configuration, tubing removal for service without special tooling. It is commonly used in DOT-regulated air brake systems on commercial vehicles as well as in general industrial pneumatic plumbing.

Compatibility

Designed for use with 5/32-inch OD tubing in DOT air brake systems and general pneumatic plumbing applications. Confirm tubing OD and material compatibility with the fitting before installation.

Installation Notes

Depressurize and bleed all air pressure from the system before removing or installing any fittings. Ensure tubing is cut cleanly and squarely, and that the tube end is free of burrs before inserting into the fitting. DOT air brake circuits must be installed in accordance with applicable federal motor vehicle safety regulations and manufacturer guidelines. Verify the fitting is fully seated by applying light pull-out force to the tubing after insertion.
