Parker 169PTCNS-4-2 90 Male Elbow 1/4 in Od 1/8 Nptf Brass

Product Description

The PARKER 169PTCNS-4-2 is a push-to-connect rigid 90-degree male elbow tube fitting designed for compressed air and pneumatic plumbing applications. It connects a 1/4-inch OD tube to a 1/8-inch NPTF male threaded port in a 90-degree orientation, allowing directional routing of tubing without bends or additional adapters. Constructed from brass with a nitrile O-ring seal, the fitting is rated to 250 psi maximum working pressure and carries DOT FMVSS 571.106 and SAE J844 compliance, making it suitable for DOT-regulated air brake systems. Installation and service are performed by licensed mechanics, fleet technicians, and plumbing or pneumatic system professionals.

This fitting is applied in air brake circuits, pneumatic control lines, and compressed air distribution systems where a tube-to-male-NPT transition at a 90-degree angle is required. Its push-to-connect design allows tubing to be inserted and locked without threaded ferrules or compression sleeves, speeding up assembly in tight routing spaces. The DOT air brake designation confirms compliance with federal motor vehicle safety standards, making it appropriate for over-the-road vehicle brake systems and associated pneumatic components. Working temperature range spans -40 degrees F to 200 degrees F, supporting a wide variety of service environments.

Compatibility

Designed as an OEM-style push-to-connect fitting for pneumatic and DOT air brake plumbing systems using 1/4-inch OD tubing with 1/8-inch NPTF male-threaded ports.

Installation Notes

Depressurize and isolate the air system completely before removing or installing any fittings. Inspect the tubing cut end for squareness and burrs before inserting into the push-to-connect collet. Thread the NPTF male end into the mating port by hand to confirm thread engagement before applying a wrench, and follow applicable SAE and DOT air brake service procedures for torque and leak testing. Leak-check all connections at full system pressure before returning the vehicle or equipment to service.
