Parker 179PTCNS-10-6 45 Male Elbow 5/8 Od 3/8 Npt Brass

Product Description

The PARKER 179PTCNS-10-6 is a push-to-connect rigid 45-degree male elbow tube fitting designed for DOT-compliant air brake systems. Constructed from brass, it connects a 5/8-inch OD tube on each tube port to a 3/8-inch male NPT thread at the center port. The push-to-connect design allows tube insertion without additional tools, reducing installation time on compressed-air plumbing runs. Rated to 250 psi maximum working pressure, it operates across a temperature range of -40 degrees F to 200 degrees F. The nitrile O-ring seals maintain integrity under the pressure cycling and vibration common to air brake service. Licensed HVAC, fleet, and pneumatic technicians install this fitting on commercial vehicle and industrial compressed-air lines.

This fitting is specified for DOT air brake applications on commercial vehicles and industrial pneumatic systems where a 45-degree change of direction is required at a male NPT port entry point. It meets SAE J2494, SAE J2494-3, SAE J844, and D.O.T. FMVSS571.106 standards, making it suitable for regulated air brake plumbing. The Tube x MNPT x Tube x Male configuration accommodates inline transitions from tube runs to threaded pipe ports without additional adapters. Technicians working on trailer, truck, or stationary compressor plumbing will find this fitting directly applicable.

Key Features

• Push-to-connect design on tube ports for fast, tool-free tube insertion
• Rigid 45-degree elbow geometry for direction changes in tight plumbing layouts
• Brass construction for corrosion resistance in air brake and pneumatic environments
• Nitrile O-ring seals rated for pressure cycling and temperature extremes
• DOT-compliant per FMVSS571.106, SAE J2494, SAE J2494-3, and SAE J844
• 250 psi maximum working pressure for air brake service duty

Compatibility

Designed as a DOT air brake fitting for commercial vehicle and industrial pneumatic plumbing systems requiring a 5/8-inch OD tube connection at a 3/8-inch male NPT port with a 45-degree angle. Confirm tube OD and NPT thread size at point of service before installation.

Installation Notes

Installation should be performed by a qualified technician familiar with DOT air brake regulations and pneumatic plumbing practices. Depressurize the air system completely and verify zero system pressure before removing or installing any fitting. Ensure the 3/8-inch NPT male threads are clean and apply appropriate thread sealant per shop practice; do not overtighten threaded connections. Tube ends must be cut cleanly and squarely to the correct OD before insertion into the push-to-connect ports to ensure a proper seal.
