Midland Industries NT65-10 Brass 90 Degree Elbow 5/8 in

Product Description

The MIDLAND INDUSTRIES NT65-10 is a 90-degree brass elbow fitting designed for air brake tubing systems. It connects 5/8-inch tube OD on both ends using a 13/16-18 thread and is rated for 150 psi service pressure across a temperature range of -40 to 200 degrees F. Constructed from brass, this fitting delivers reliable sealing performance under the pressure and vibration demands typical of commercial vehicle and heavy-duty air brake circuits. Licensed HVAC and fleet service technicians use this fitting when routing or repairing nylon tubing runs that require a 90-degree change in direction.

This fitting is specified for use with SAE J844 Type A and Type B NT nylon tubing, making it appropriate for air brake supply and control lines in truck, trailer, and bus applications. The 90-degree elbow configuration is commonly used when tubing must transition around frame rails, bulkheads, or chassis components where straight connections are not practical. It belongs to the MAF/USA Brass Fittings air brake elbow product family.

Installation Notes

Installation should be performed by a qualified technician familiar with DOT air brake system requirements. Before servicing any air brake fitting, depressurize the system completely and verify zero pressure at the line before disconnecting tubing. Use appropriate tube insertion depth and ensure the tubing is cut cleanly and squarely before insertion. Inspect the fitting and tubing for damage before assembly and do not exceed the rated working pressure of 150 psi.
