Parker 169PTC-8-4 90 Male Elbow 1/2 Od 1/4 Nptf Brass Dot

Product Description

The PARKER 169PTC-8-4 is a push-to-connect 90-degree male elbow tube fitting designed for air brake and pneumatic fluid-conveyance systems. It connects 1/2-inch OD tubing to a 1/4-inch NPTF male threaded port at a right angle, allowing directional routing in tight plumbing runs. Constructed from brass with a nitrile O-ring seal, it is rated to 250 psi maximum working pressure and handles temperatures from -40 degrees F to 200 degrees F. This fitting meets D.O.T. FMVSS 571.106, SAE J2494, SAE J2494-3, and SAE J844 standards. It is installed by licensed diesel technicians, fleet maintenance professionals, and commercial vehicle service specialists.

This fitting is specified for D.O.T.-compliant air brake tubing assemblies on commercial trucks, trailers, and buses. The push-to-connect design allows fast, tool-free tube insertion while maintaining pressure integrity required by federal motor vehicle safety standards. It is also suitable for industrial pneumatic plumbing where NPTF male porting and 1/2-inch OD nylon or poly tubing are in use. The 90-degree elbow geometry is particularly useful where a straight fitting would create excessive bend radius or interfere with chassis components.

Key Features

• Push-to-connect design for fast, tool-free tube insertion with 1/2-inch OD tubing
• 90-degree male elbow routes tubing at right angles to NPTF-threaded ports
• Brass body construction for corrosion resistance in air brake environments
• Nitrile O-ring seal maintains pressure integrity across the rated temperature range
• Rated to 250 psi maximum working pressure
• D.O.T. certified fitting compliant with FMVSS 571.106, SAE J2494, SAE J2494-3, and SAE J844

Compatibility

Designed as a D.O.T. air brake fitting for use with 1/2-inch OD air brake tubing terminated at 1/4-inch NPTF male-ported valves, manifolds, or control components in commercial vehicle brake systems.

Installation Notes

Installation should be performed by a qualified diesel mechanic or air brake system technician in accordance with applicable D.O.T. and SAE service procedures. Depressurize the air brake system completely and drain the reservoirs before removing or installing any fittings. Ensure the NPTF threads are clean and apply an appropriate thread sealant compatible with compressed air systems. Verify tube is cut square and fully seated in the push-to-connect collar before pressurizing; pull back on the tube gently to confirm retention.
