Parker 179PTCNS-10-8 45 Male Elbow 5/8 Od 1/2 Npt Brass

Product Description

The PARKER 179PTCNS-10-8 is a push-to-connect rigid 45-degree male elbow tube fitting designed for use in DOT-compliant air brake systems. Constructed from brass, it connects 5/8-inch OD tubing to a 1/2-inch male NPT port at a 45-degree angle, allowing directional routing in tight plumbing configurations. The push-to-connect design enables fast, tool-free tube insertion while maintaining a secure, leak-resistant seal. Rated to 250 psi maximum working pressure, this fitting handles the demanding pressure cycles common in commercial vehicle and industrial air brake circuits. The nitrile O-ring provides reliable sealing across a wide temperature range, from -40 degrees F to 200 degrees F.

This fitting is intended for air brake tubing applications on commercial vehicles and related pneumatic systems where DOT compliance is required. It meets SAE J2494, SAE J2494-3, SAE J844, and DOT FMVSS571.106 standards, making it appropriate for use in federally regulated brake line assemblies. Typically installed by commercial vehicle technicians, fleet maintenance professionals, and industrial pneumatic system mechanics, this elbow is suited for locations where a 45-degree change of direction is needed between a tube run and a male-threaded port.

Key Features

• Push-to-connect design for fast, tool-free tube insertion and secure retention
• Rigid 45-degree male elbow geometry for directional routing in constrained spaces
• Brass construction for corrosion resistance in air brake environments
• Rated to 250 psi maximum working pressure
• Nitrile O-ring seal rated from -40 degrees F to 200 degrees F
• DOT compliant — meets FMVSS571.106, SAE J2494, SAE J2494-3, and SAE J844

Compatibility

Designed as a DOT air brake fitting for pneumatic tubing systems using 5/8-inch OD tubing and 1/2-inch male NPT connections in commercial vehicle and industrial applications where applicable DOT and SAE standards are required.

Installation Notes

Installation should be performed by qualified commercial vehicle or industrial pneumatic technicians familiar with DOT air brake system requirements. Depressurize the air system completely and verify zero pressure before removing or installing any fittings. Insert tubing fully to the tube stop to ensure the collet engages properly and the O-ring seats for a leak-free connection. Verify compliance with applicable DOT and SAE standards for the specific vehicle or system being serviced.
