Parker 172PTC-8-8 Swivel Male Branch Tee 1/2 in Od Npt Brass

Product Description

The PARKER 172PTC-8-8 is a push-to-connect swivel male branch tee fitting designed for use in pneumatic tubing systems, particularly DOT-rated air brake circuits. Constructed from brass with a nitrile O-ring, this fitting accepts 1/2-inch OD tubing on the tube ports and connects to a 1/2-inch male NPT threaded port. It is rated to a maximum working pressure of 250 psi and handles temperatures from -40 degrees F to 200 degrees F. The swivel branch configuration simplifies routing during installation, reducing the need for additional adapters. Licensed HVAC technicians, plumbers, and fleet maintenance professionals working on air brake systems are the primary installers.

This fitting is suited for DOT-compliant air brake tubing assemblies in commercial vehicles and pneumatic control systems where a branch tee connection is required between push-to-connect tubing runs and a male NPT threaded port. It meets DOT FMVSS 571.106, SAE J2494, SAE J2494-3, and SAE J844 standards, making it appropriate for regulated air brake applications. The swivel male branch design allows the NPT port to be oriented independently of the tube legs, which aids alignment in tight installations.

Key Features

• Push-to-connect tube ports accept 1/2-inch OD tubing without tools for fast assembly
• Swivel male branch allows NPT port orientation independent of tubing alignment
• Brass construction provides corrosion resistance in pneumatic and air brake environments
• Nitrile O-ring seals rated for -40 degrees F to 200 degrees F service range
• 250 psi maximum working pressure meets DOT air brake circuit requirements
• Meets DOT FMVSS 571.106, SAE J2494, SAE J2494-3, and SAE J844 standards

Compatibility

Designed as a DOT-rated air brake fitting for push-to-connect pneumatic tubing systems using 1/2-inch OD tubing and 1/2-inch male NPT threaded connections. Suitable for systems requiring compliance with DOT FMVSS 571.106, SAE J2494, SAE J2494-3, and SAE J844.

Installation Notes

Installation should be performed by a qualified technician familiar with DOT air brake system regulations. Depressurize and drain the air system completely before removing or installing any fittings. Ensure NPT threads are sealed with an appropriate thread sealant rated for pneumatic service and that tubing is cut cleanly and squarely before insertion into the push-to-connect ports. Verify the system meets applicable DOT and SAE standards upon completion.
