Parker 172PTCNS-8-6 Male Branch Tee 1/2in Od 3/8in Npt Brass

Product Description

The PARKER 172PTCNS-8-6 is a push-to-connect rigid male branch tee fitting designed for pneumatic tube assemblies in commercial vehicle and industrial air brake systems. Constructed from brass, this fitting connects 1/2-inch OD tubing to a 3/8-inch NPT male port with a third tube leg branching off the body. It is rated to 250 psi maximum working pressure and operates across a temperature range of -40 degrees F to 200 degrees F. The nitrile O-ring provides a reliable seal against air loss. The push-to-connect design allows quick tube insertion without additional tools at the tube end, reducing assembly time in high-volume or field-repair situations.

This fitting is classified as a DOT air brake fitting and meets DOT FMVSS 571.106, SAE J2494, SAE J2494-3, and SAE J844 standards. It is suited for use in air brake line assemblies on trucks, trailers, and buses where a rigid tee branch connection is required. Fleet maintenance technicians and brake system installers typically use this fitting when routing compressed air lines through a branch point. The 1/2-inch OD tube-to-tube legs combined with the 3/8-inch NPT male thread make it compatible with common air brake plumbing configurations found in commercial vehicle applications.

Key Features

• Push-to-connect tube ends accept 1/2-inch OD tubing without ferrules or compression nuts
• 3/8-inch NPT male branch port for direct connection to valves, manifolds, or ported components
• 250 psi maximum working pressure rated for air brake service
• Nitrile O-ring sealing element for reliable air-tight performance
• Brass body construction for corrosion resistance in pneumatic environments
• Meets DOT FMVSS 571.106, SAE J2494, SAE J2494-3, and SAE J844 standards

Compatibility

Rated as a DOT air brake fitting per FMVSS 571.106 and SAE J844 standards. Designed for use with 1/2-inch OD tubing and 3/8-inch NPT male ported components in commercial vehicle compressed air brake systems.

Installation Notes

Installation is performed by licensed brake system technicians or qualified fleet maintenance personnel. Depressurize and drain the air system fully before removing or installing any air brake fittings. Ensure tubing is cut cleanly and squarely and is free of burrs before inserting into the push-to-connect port. Verify all connections meet applicable DOT and SAE air brake plumbing requirements before returning the vehicle to service.
