The PARKER 170PTCNS-8-4 is a push-to-connect rigid 90-degree female elbow tube fitting manufactured from brass. It connects a 1/2-inch OD tube to a 1/4-inch NPTF female port, making a right-angle transition in compressed air and pneumatic brake line systems. With a maximum working pressure of 250 psi and a temperature range of -40 degrees F to 200 degrees F, this fitting is rated for DOT air brake service per FMVSS 571.106, SAE J2494, SAE J2494-3, and SAE J844. Licensed HVAC technicians, fleet mechanics, and pneumatic system installers use this fitting where a compact, tool-free tube connection at a female port is required.
This fitting is designed for DOT-compliant air brake and pneumatic tubing systems, including commercial vehicle brake lines and industrial compressed air circuits. The push-to-connect design speeds up installation in tight spaces where wrench access is limited. The NPTF thread type provides a pressure-tight mechanical seal without requiring additional sealant in many installations. The Nitrile O-ring provides reliable sealing across the rated temperature range, making this fitting appropriate for both under-hood and cab-chassis routing environments.
Designed for DOT-compliant air brake and pneumatic systems using 1/2-inch OD tubing with a 1/4-inch NPTF female port connection, conforming to FMVSS 571.106, SAE J2494, SAE J2494-3, and SAE J844 standards.
Installation should be performed by a qualified mechanic or pneumatic systems technician. Depressurize the air system fully before removing or installing any fittings. Ensure tubing is cut cleanly and squarely and is free of burrs before inserting into the push-to-connect port. Verify NPTF thread engagement meets applicable DOT and SAE service requirements before returning the system to service.
