Parker 171PTC-8-8 Swivel Male Run Tee 1/2 in Od Brass

Product Description

The PARKER 171PTC-8-8 is a push-to-connect swivel male run tee tube fitting designed for pneumatic and air brake plumbing systems. It connects 1/2-inch OD tubing on two ports to a 1/2-inch male NPTF threaded port, allowing a branch connection without cutting into an existing line. Constructed from brass with a nitrile O-ring seal, this fitting handles pressures up to 250 psi and operates across a temperature range of -40 degrees F to 200 degrees F. It carries D.O.T. FMVSS571.106, SAE J2494, SAE J2494-3, and SAE J844 certifications, making it compliant for use in D.O.T.-regulated air brake circuits.

This fitting is used in commercial vehicle air brake systems, heavy-duty pneumatic plumbing, and industrial compressed-air applications requiring a reliable run tee with a swivel male NPT branch outlet. The push-to-connect design speeds up assembly on truck chassis, trailer air lines, and shop pneumatic distribution systems. The swivel feature allows the NPTF port to be oriented after installation, reducing the need to adjust adjacent components. Overall installed length is 3.0 inches.

Key Features

• Push-to-connect tube ports accept 1/2-inch OD tubing without additional tools or ferrules
• Swivel male NPTF thread allows post-assembly port orientation
• Brass body provides corrosion resistance in compressed-air and air brake environments
• Nitrile O-ring seals maintain integrity across -40 degrees F to 200 degrees F
• Rated to 250 psi maximum working pressure
• D.O.T. certified per FMVSS571.106, SAE J2494, SAE J2494-3, and SAE J844

Compatibility

Designed as a D.O.T.-compliant air brake fitting for use with 1/2-inch OD nylon or poly tubing in commercial vehicle and heavy-duty pneumatic systems meeting SAE J844 tube specifications.

Installation Notes

Installation is performed by licensed mechanics or qualified pneumatic system technicians. Depressurize the air system completely before removing or installing any fittings. Insert tubing fully into the push-to-connect port until it seats, then verify retention by pulling back on the tube with firm hand pressure. Thread the NPTF port to the mating component before locking the swivel in final position; inspect for leaks after pressurizing the system.
