Parker 68PTC-8-8 Push-to-connect Male Connector 1/2 in

Product Description

The PARKER 68PTC-8-8 is a push-to-connect male connector tube fitting designed for air brake and pneumatic plumbing systems. It connects tube to male NPT on both ends using a push-to-connect tube interface, allowing fast, tool-free tube insertion without ferrules or compression sleeves. Constructed from brass with a nitrile O-ring seal, the fitting handles working pressures up to 250 psi and operates across a temperature range of -40 degrees F to 200 degrees F. The 1/2 inch OD tube connection pairs with a 1/2 inch NPTF male thread. This fitting meets D.O.T. FMVSS571.106, SAE J2494, and SAE J2494-3 standards, making it a compliant choice for federally regulated air brake circuit repairs and new installations.

This fitting is suited for commercial vehicle air brake systems, fleet maintenance, and industrial pneumatic plumbing where a reliable tube-to-NPT male inline connection is required. The push-to-connect design speeds up installation on compressed-air lines in trucks, trailers, and heavy equipment. It is also applicable in shop air systems and general pneumatic circuits where brass fittings rated to 250 psi are specified. The D.O.T. rating makes it the correct choice when working on federally regulated vehicle brake circuits.

Key Features

• Push-to-connect tube interface accepts 1/2 inch OD tubing without tools or ferrules
• 1/2 inch NPTF male thread for a pressure-tight seal on NPT ported components
• Brass construction for corrosion resistance in pneumatic service
• Nitrile O-ring seal rated for -40 degrees F to 200 degrees F operating range
• 250 psi maximum working pressure
• D.O.T. FMVSS571.106 compliant — approved for air brake circuit use
• Meets SAE J2494 and SAE J2494-3 standards

Compatibility

Designed for use in D.O.T.-regulated air brake systems and industrial pneumatic plumbing applications requiring a 1/2 inch OD push-to-connect tube connection with a 1/2 inch NPTF male thread port.

Installation Notes

Installation is typically performed by licensed fleet mechanics, pneumatic system technicians, or plumbers familiar with air brake regulations. Depressurize and isolate the air circuit completely before removing or installing any fitting. Ensure the NPTF thread is clean and apply thread sealant appropriate for pneumatic service per shop practice. Push tubing fully into the connector until it seats to achieve a proper seal — partial insertion will result in leakage or blowout under pressure.
