Parker 169PTCNS-8-6 90 Male Elbow Fitting 1/2 in Od Brass

Product Description

The PARKER 169PTCNS-8-6 is a push-to-connect rigid 90-degree male elbow tube fitting constructed from brass. It accepts 1/2-inch OD tubing on the push-to-connect ends and provides a 3/8-inch NPTF male threaded connection. Rated to 250 psi maximum working pressure, the fitting is designed for DOT-compliant air brake systems on commercial vehicles. The nitrile O-ring seals the tube connection and performs across a service temperature range of -40 degrees F to 200 degrees F. Installation requires no tools on the tube side — tubing inserts and locks without ferrules or compression sleeves. This fitting is installed by fleet service technicians and licensed air brake system specialists.

This fitting is specified for DOT air brake plumbing on heavy trucks, trailers, and other commercial motor vehicles where push-to-connect assembly speed and positive sealing are required. The tube-to-MNPT configuration allows the fitting to transition between nylon or polyethylene air brake tubing and a threaded port on a valve body, manifold, or bulkhead component. It is appropriate for use where DOT FMVSS 571.106 and SAE J844 compliance is required by regulation.

Key Features

• Push-to-connect on tube end — no ferrule or compression ring required
• Rigid 90-degree elbow routes tubing in tight spaces without field bending
• Brass body construction for corrosion resistance in mobile and stationary air systems
• Nitrile O-ring for reliable sealing across wide temperature swings
• DOT-compliant — meets FMVSS 571.106, SAE J2494, SAE J2494-3, and SAE J844 standards
• 250 psi maximum working pressure rating

Compatibility

Designed for DOT-compliant air brake tubing systems requiring a 1/2-inch OD push-to-connect tube connection and a 3/8-inch NPTF male port transition. Meets SAE J844 air brake tubing system requirements.

Installation Notes

Installation must be performed by technicians qualified to service DOT air brake systems in accordance with applicable federal and state regulations. Depressurize the air system fully and drain reservoir tanks before removing or installing any air brake fitting. Ensure tubing is cut cleanly and squarely and that the tube end is free of burrs before inserting into the push-to-connect port. Thread the NPTF male end into the mating port using an appropriate thread sealant compatible with the system medium, and verify all connections for leaks before returning the vehicle to service.
