Parker 179PTC-8-8 Swivel 45 Male Elbow 1/2in Od Npt Brass

Product Description

The PARKER 179PTC-8-8 is a brass push-to-connect swivel 45-degree male elbow fitting designed for air brake and pneumatic tube systems. It connects a 1/2-inch OD tube to a 1/2-inch male NPT port at a 45-degree angle, allowing directional routing without bending tube or adding extra fittings. The swivel design simplifies alignment during installation. Rated to 250 psi maximum working pressure, this fitting meets D.O.T. FMVSS 571.106, SAE J2494, SAE J2494-3, and SAE J844 standards, making it a code-compliant choice for commercial vehicle and industrial air brake plumbing. The nitrile O-ring provides a reliable seal across a wide service temperature range.

This fitting is used in D.O.T.-regulated air brake systems on commercial trucks, trailers, and heavy equipment where 1/2-inch OD nylon or polyethylene tubing connects to a male NPT port at an angled approach. It is also suitable for general-purpose compressed air and pneumatic control lines operating within rated pressure and temperature limits. Fleet maintenance shops, mobile equipment technicians, and industrial maintenance crews install this fitting when routing air lines in tight or angled spaces where a straight fitting would require excessive tube bending.

Key Features

• Push-to-connect design allows fast, tool-free tube insertion and secure retention
• Swivel body allows the NPT thread to be torqued to the port without twisting the tubing
• 45-degree angle simplifies routing in confined spaces
• Brass construction provides corrosion resistance and durability in air brake service
• Nitrile O-ring seals across a -40 degrees F to 200 degrees F operating temperature range
• Meets D.O.T. FMVSS 571.106, SAE J2494, SAE J2494-3, and SAE J844 standards

Compatibility

Designed as a D.O.T.-compliant air brake fitting for use with 1/2-inch OD nylon or polyethylene air brake tubing connecting to 1/2-inch male NPT ports on commercial vehicle and industrial pneumatic systems.

Installation Notes

Installation should be performed by a qualified technician familiar with D.O.T. air brake system requirements. Depressurize the air system completely before removing or installing fittings. Thread the NPT end into the port using appropriate thread sealant compatible with air service before inserting the tube into the push-to-connect end until it bottoms out and is positively retained. After pressurizing the system, verify the connection is leak-free using an approved leak-detection method before returning the vehicle or equipment to service.
