Parker 68PTC-5/32-4 Push-to-connect Male Connector Fitting

Product Description

The PARKER 68PTC-5/32-4 is a brass push-to-connect male connector fitting designed for tube-to-male NPT tube connections in compressed air and fluid line applications. It accepts 5/32 inch OD tubing on each tube end and threads into a 1/4 inch NPT male port, providing a secure, tool-free tube connection at rated pressures up to 250 psi. The fitting carries D.O.T. FMVSS571.106, SAE J2494, and SAE J2494-3 certifications, classifying it as a D.O.T. air brake fitting suitable for mobile and vehicle air brake systems. Licensed plumbers, fleet mechanics, and HVAC technicians install this type of fitting in pneumatic control lines, air brake circuits, and instrument tubing runs.

This fitting is rated for service from -40 degrees F to 200 degrees F, making it compatible with a wide range of pneumatic and fluid system environments, including under-hood and chassis-mounted air brake plumbing. The push-to-connect design allows tubing to be inserted and locked without tools, speeding up installation in tight or hard-to-reach locations. Its brass construction and nitrile O-ring provide resistance to corrosion and compatibility with air, water, and common pneumatic media. It is suited for both OEM assembly and field repair applications where D.O.T.-rated air brake fittings are required.

Key Features

• Push-to-connect design locks 5/32 inch OD tubing without tools
• Brass body for corrosion resistance in air and fluid service
• Nitrile O-ring construction for reliable sealing across temperature range
• Rated to 250 psi maximum working pressure
• D.O.T. certified air brake fitting meeting FMVSS571.106, SAE J2494, and SAE J2494-3 standards
• Operating range of -40 degrees F to 200 degrees F

Compatibility

Designed as a D.O.T.-rated air brake fitting for pneumatic systems using 5/32 inch OD tubing with 1/4 inch NPT male port connections, consistent with vehicle air brake and compressed air plumbing circuits requiring SAE J2494 and SAE J2494-3 compliance.

Installation Notes

Installation is typically performed by fleet mechanics, pneumatic system technicians, or licensed plumbers working on air brake or compressed air systems. Depressurize and isolate the air line completely before removing or installing any fitting. Ensure tubing is cut square, deburred, and clean before insertion into the push-to-connect port. Follow D.O.T. and SAE guidelines for air brake system assembly and inspection intervals.
