Parker 171PTC-8-6 Push-to-connect Tube Male Npt Fitting

Product Description

The PARKER 171PTC-8-6 is a brass push-to-connect tube fitting with a male NPT end, designed for use in pneumatic and fluid transfer systems requiring fast, reliable tube connections. This fitting connects a 1/2 inch OD tube on both ends to a 3/8 inch male NPTF thread at the center port. It is rated for up to 250 psi maximum working pressure and carries a D.O.T. Air Brake designation, making it suitable for regulated brake system plumbing. The nitrile o-ring construction supports a wide service temperature range. Licensed technicians and fleet mechanics working on air brake or pneumatic lines are the primary installers.

This fitting is commonly used in commercial vehicle air brake systems, industrial pneumatic plumbing, and fluid handling lines where a push-to-connect tube-to-tube configuration with an intermediate male NPT branch or inline thread is required. The D.O.T. Air Brake rating means it meets federal motor vehicle safety standards for pressurized brake circuit use. It is appropriate for both residential and light commercial pneumatic applications within its rated pressure and temperature limits. Installers working on compressed air distribution or mobile equipment pneumatics will find this fitting applicable across a range of standard configurations.

• Nitrile o-ring material suited for petroleum-based and air media

Compatibility

Designed for use with 1/2 inch OD tubing and 3/8 inch NPTF male threaded ports in D.O.T.-compliant air brake systems and general pneumatic plumbing applications. No specific equipment model compatibility was provided by the manufacturer for this SKU.

Installation Notes

Installation should be performed by a qualified technician familiar with D.O.T. air brake regulations and pneumatic system requirements. Depressurize the air system completely before removing or installing any fittings. Ensure tubing is cut cleanly and squarely, free of burrs, and inserted to full depth before pressurizing. NPTF threads should be inspected and mated only to compatible tapered female threads; do not cross-thread or overtighten.
