Midland Industries NT69-88VS 90 Degree Brass Elbow 1/2 in

Product Description

The MIDLAND INDUSTRIES NT69-88VS is a 90-degree brass elbow fitting designed for air brake tubing systems. It connects 1/2-inch tube OD on one end to a 1/2-inch male NPTF thread on the other, providing a secure right-angle transition in pressurized pneumatic lines. The fitting is rated to 150 psi and handles temperatures from -40 to 200 degrees F, making it suitable for the thermal cycling demands of commercial vehicle and heavy-equipment air brake circuits. Constructed from brass with an 11/16-20 thread specification, this fitting is compatible with SAE J844 Type A and B NT nylon tubing. Fleet maintenance technicians and commercial vehicle service shops are the primary installers.

This fitting is used in air brake pneumatic systems on commercial trucks, trailers, and heavy equipment where a 90-degree directional change is required in the tubing run. It is specified for use with SAE J844 Type A and B NT nylon tubing, which is the standard air brake tubing type in North American fleet applications. The right-angle configuration allows routing around frame members, bulkheads, or other components without bending the tubing itself, reducing stress on the line.

Compatibility

Designed for use with SAE J844 Type A and B NT nylon tubing in air brake pneumatic systems.

Installation Notes

Installation should be performed by a qualified commercial vehicle technician or fleet maintenance professional familiar with air brake systems. Depressurize the air brake system completely before removing or installing any fittings. Ensure the tubing is cut cleanly and seated fully in the fitting before tightening. Verify the completed connection holds pressure and shows no leaks before returning the vehicle or equipment to service.
