Parker 171PTCNS-3-2 Rigid Male Run Tee 3/16in Od 1/8in Npt

Product Description

The PARKER 171PTCNS-3-2 is a push-to-connect rigid male run tee fitting designed for use in compressed air and fluid transfer line assemblies. Constructed from brass, it connects tubing on two run ports and a male NPT port on the branch, allowing a straight tube run to branch off to a threaded fitting in a single, compact body. The fitting accepts 3/16 inch OD tubing on the tube ports and threads into a 1/8 inch NPT female port. It is rated to 250 psi maximum working pressure and carries D.O.T. certification for air brake service, making it a trusted choice for licensed technicians working on commercial vehicle and heavy-equipment air brake circuits.

This fitting is commonly specified in D.O.T.-regulated air brake plumbing on trucks, trailers, and buses, as well as in pneumatic control circuits where a push-to-connect tee with a threaded branch is required. The brass construction suits dry and lubricated compressed air service across a wide temperature range. HVAC and refrigeration technicians also use fittings of this type in low-pressure pneumatic control lines. It is sold individually and is appropriate for both original installation and field repair work.

Key Features

• D.O.T. certified air brake fitting meeting FMVSS 571.106, SAE J2494, SAE J2494-3, and SAE J844 standards
• Push-to-connect tube ports accept 3/16 inch OD tubing without tools for fast, reliable connections
• 1/8 inch NPT male branch threads into standard female NPT ports
• 250 psi maximum working pressure for air brake and pneumatic control applications
• Brass body with nitrile O-ring seals for compatibility with compressed air service
• Rated from -40 degrees F to 200 degrees F operating temperature range

Compatibility

Designed as a D.O.T.-compliant replacement or service fitting for air brake and pneumatic tube assemblies using 3/16 inch OD tubing with 1/8 inch NPT threaded connections, per SAE J844 and SAE J2494 specifications.

Installation Notes

Installation should be performed by a qualified technician familiar with D.O.T. air brake regulations and applicable SAE standards. Depressurize and drain the air brake or pneumatic system completely before removing or installing fittings. Ensure tubing is cut cleanly and squarely and that the OD is free of burrs or scoring before inserting into the push-to-connect port. NPT threads should be sealed with an approved thread sealant compatible with compressed air service; do not overtighten, as brass fittings are susceptible to thread damage.
