Parker 170PTCNS-4-4 Brass 90 Female Elbow Ptc Fitting 1/4 in

Product Description

The PARKER 170PTCNS-4-4 is a push-to-connect brass rigid 90-degree female elbow tube fitting designed for pneumatic plumbing in air brake and fluid conveyance systems. It accepts 1/4 inch OD tubing on both tube ports and connects to a 1/4 inch NPTF female thread at the elbow body. The fitting is rated to 250 psi maximum working pressure and handles temperatures from -40 degrees F to 200 degrees F. A nitrile O-ring provides the tube-port seal. This fitting is DOT-compliant under FMVSS 571.106 and meets SAE J2494 and SAE J844 standards. Licensed plumbers, HVAC technicians, and fleet brake system mechanics install this type of fitting in air brake line assemblies, pneumatic controls, and compressed-air distribution applications.

The 170PTCNS-4-4 is suited for commercial vehicle air brake circuits, industrial pneumatic systems, and compressed-air plumbing where a 90-degree direction change is needed between a tube run and a female NPT port. The tube-to-FNPT-to-tube configuration allows it to serve as a tee-style branch or an inline elbow depending on the circuit layout. Its DOT compliance makes it appropriate for regulated air brake installations on trucks, trailers, and buses operating under FMVSS and SAE air brake plumbing requirements.

Key Features

• Push-to-connect tube ports accept 1/4 inch OD tubing without tools for fast, reliable connections
• Brass body construction provides corrosion resistance in air and hydraulic-compatible fluid environments
• 250 psi maximum working pressure rated for commercial pneumatic and air brake service
• Wide temperature range: -40 degrees F to 200 degrees F
• Nitrile O-ring seal material for compatibility with air and common brake system media
• DOT compliant to FMVSS 571.106, SAE J2494, SAE J2494-3, and SAE J844

Compatibility

Designed as a DOT-compliant air brake fitting for pneumatic systems using 1/4 inch OD tubing and 1/4 inch NPTF female threaded ports, conforming to SAE J844 air brake tubing standards.

Installation Notes

This fitting is typically installed by qualified brake system mechanics or licensed plumbers working on compressed-air circuits. Depressurize and drain the air system fully before disconnecting or installing any fittings. Insert tubing straight and fully into the push-to-connect port until it seats against the internal stop before pressurizing. NPTF threads are designed for dry-seal engagement, but consult applicable DOT, FMVSS, and SAE specifications for thread engagement and assembly requirements on regulated air brake systems.
