Parker 179PTC-8-6 Swivel 45 Elbow 1/2 Od 3/8 Npt Brass

Product Description

The PARKER 179PTC-8-6 is a brass push-to-connect swivel 45-degree male elbow fitting designed for air brake and pneumatic tubing systems. It connects 1/2-inch OD tubing to a 3/8-inch male NPT port, allowing a 45-degree change in line direction with a swivel function that simplifies alignment during installation. Rated to 250 psi maximum working pressure and suitable for temperatures from -40 degrees F to 200 degrees F, this fitting meets DOT FMVSS 571.106, SAE J2494, SAE J2494-3, and SAE J844 standards. The nitrile O-ring provides a reliable seal in compressed air service. Trade professionals trust this fitting for demanding mobile equipment and commercial vehicle air brake plumbing.

This fitting is used in DOT-compliant air brake systems on commercial trucks, trailers, and other motor vehicles where push-to-connect tubing must transition to a male NPT port at a 45-degree angle. The swivel feature allows the NPT end to be threaded in fully without twisting the tubing run. Typical installers include diesel mechanics, fleet maintenance technicians, and trailer builders working with air brake tubing regulated under DOT standards.

Installation Notes

Installation should be performed by a qualified technician familiar with DOT air brake system requirements. Depressurize the air system completely before disconnecting or installing any fittings. Apply thread sealant appropriate for pneumatic service to the NPT threads before assembly. After installation, pressurize the system and verify there are no leaks before returning the vehicle or equipment to service.
