Parker 171PTCNS-4-6-4 Male Run Tee Fitting Brass Dot

Product Description

The PARKER 171PTCNS-4-6-4 is a push-to-connect rigid male run tee fitting designed for use in pneumatic tubing systems requiring a reliable, tool-free tube connection with a male NPT branch port. Constructed from brass with a nitrile O-ring, it connects tube-to-tube along the run while providing a 1/4-inch NPTF male branch outlet. It carries a maximum working pressure of 250 psi and is rated for temperatures from -40 degrees F to 200 degrees F. This fitting meets D.O.T. FMVSS571.106, SAE J2494, SAE J2494-3, and SAE J844 standards, making it a compliant choice for D.O.T. air brake applications. HVAC technicians, plumbers, and fleet maintenance professionals install this type of fitting in compressed air and fluid line assemblies.

This fitting is suited for light commercial and heavy-duty vehicle air brake systems as well as general pneumatic service lines where a tee with a male NPT branch is required. The 1/4 x 3/8 inch OD tube configuration and NPTF thread make it compatible with standard air brake tubing circuits in transportation and industrial environments. Its push-to-connect design speeds up assembly without the need for ferrules or compression tools, a practical advantage in high-volume service or repair scenarios.

Key Features

• Push-to-connect design accepts 1/4 inch and 3/8 inch OD tubing on the run ports with no ferrules or compression tools required
• 1/4 inch NPTF male branch port provides a leak-resistant threaded connection to ported components or manifolds
• Rated to 250 psi maximum working pressure for demanding pneumatic service
• Brass body with nitrile O-ring offers corrosion resistance and compatibility with air and compatible fluid media
• D.O.T. air brake fitting compliant with FMVSS571.106, SAE J2494, SAE J2494-3, and SAE J844
• Wide service temperature range of -40 degrees F to 200 degrees F suits both mobile and stationary applications

Compatibility

Designed as a D.O.T.-compliant air brake fitting for use in vehicle air brake tubing systems and general pneumatic plumbing where Tube x MNPT x Tube x Male push-to-connect rigid tee connections are specified.

Installation Notes

Installation should be performed by a qualified technician familiar with D.O.T. air brake regulations and pneumatic system service procedures. Depressurize the system completely before removing or installing any fittings. Ensure tubing is cut square, deburred, and inserted fully to the depth stop before system pressurization. Thread engagement at the NPTF port should be made with an appropriate thread sealant per the system manufacturer's recommendations and applicable codes.
