Parker 170PTC-4-2 Swivel 90 Female Elbow 1/4 in Od Brass

Product Description

The PARKER 170PTC-4-2 is a push-to-connect swivel 90-degree female elbow tube fitting manufactured from brass. It connects tubing with a 1/4-inch outside diameter to a 1/8-inch NPTF female port, providing a right-angle flow path in a compact, swivelable body. The fitting is rated for 250 psi maximum working pressure and handles temperatures from -40 degrees F to 200 degrees F. Designed as a D.O.T. air brake fitting, it meets D.O.T. FMVSS571.106, SAE J2494, SAE J2494-3, and SAE J844 standards. Licensed technicians and fleet mechanics install this fitting in compressed-air brake and pneumatic control line applications where a secure, leak-free push-to-connect termination at a female NPT port is required.

This fitting is suited for use in commercial vehicle air brake systems, pneumatic control lines, and similar compressed-air plumbing where D.O.T.-compliant components are required. The swivel body allows the elbow to be oriented after assembly without disturbing the tube connection, simplifying routing in tight or congested installations. The nitrile O-ring provides a reliable seal across the full rated temperature range, making this fitting appropriate for both heated cab environments and cold-weather outdoor service.

Key Features

• Push-to-connect design allows tool-free tube insertion for fast, secure assembly
• Swivel elbow body enables post-assembly orientation without disconnecting tubing
• Rated to 250 psi maximum working pressure
• Nitrile O-ring seal rated from -40 degrees F to 200 degrees F
• D.O.T. air brake fitting compliant with FMVSS571.106, SAE J2494, SAE J2494-3, and SAE J844
• Brass construction for corrosion resistance in compressed-air service

Compatibility

Designed as a D.O.T.-compliant air brake fitting for compressed-air brake and pneumatic tubing systems using 1/4-inch OD tubing terminating at a 1/8-inch NPTF female port.

Installation Notes

Installation should be performed by a qualified technician familiar with D.O.T. air brake system requirements. Depressurize the air brake system fully before removing or installing any fittings. Ensure the 1/8-inch NPTF female port threads are clean and undamaged before assembly; the NPTF thread form creates a metal-to-metal seal that does not require thread tape when properly engaged. Push tubing fully into the collet until it bottoms out before applying system pressure, and verify there are no leaks at operating pressure before returning the vehicle to service.
