Parker 172PTCNS-4-2 Male Branch Tee 1/4 in Od 1/8 Npt Brass

Product Description

The PARKER 172PTCNS-4-2 is a push-to-connect rigid male branch tee fitting designed for pneumatic and air brake plumbing applications. Constructed from brass, this fitting accepts 1/4-inch outside diameter tubing on two ports and terminates with a 1/8-inch male NPT thread on the branch. It is rated to 250 psi maximum working pressure and handles a temperature range of -40 degrees F to 200 degrees F. The nitrile O-ring provides a reliable seal in compressed-air service. Licensed plumbers, HVAC technicians, and fleet maintenance mechanics install this type of fitting in DOT-regulated air brake systems and pneumatic control lines.

The 172PTCNS-4-2 is classified as a DOT air brake fitting, meeting D.O.T. FMVSS571.106, SAE J2494, SAE J2494-3, and SAE J844 standards. It is suited for rigid tube routing in commercial vehicle air brake circuits, pneumatic control systems, and compressed-air distribution lines where a tee connection with a male NPT branch is required. The push-to-connect design allows tubing to seat and lock without additional tools, reducing assembly time in production or field repair settings.

Key Features

• Push-to-connect design accepts 1/4-inch OD tubing on two ports for tool-free tube insertion
• 1/8-inch male NPT branch thread for direct connection to ports, valves, or manifolds
• Brass construction for corrosion resistance in compressed-air service
• Nitrile O-ring sealing element rated for broad temperature and pressure service
• 250 psi maximum working pressure for pneumatic circuit applications
• Compliant with D.O.T. FMVSS571.106, SAE J2494, SAE J2494-3, and SAE J844

Compatibility

Designed as a DOT-compliant air brake fitting for use with 1/4-inch OD rigid tubing in commercial vehicle air brake systems and pneumatic control plumbing that requires a male NPT branch tee configuration.

Installation Notes

Depressurize and isolate the air system completely before servicing any fitting. Ensure tubing cut ends are clean, square, and free of burrs before insertion into the push-to-connect ports. Apply thread sealant appropriate for NPT connections on the male branch per applicable system requirements. Installation and inspection of DOT air brake fittings should be performed by qualified technicians familiar with applicable federal motor vehicle safety standards.
