Midland Industries HE68G-68 Brass Hose Mpt Adapter Spring

Product Description

The MIDLAND INDUSTRIES HE68G-68 is a brass hose-end connector with spring designed for air brake plumbing applications. It transitions a 3/8 inch hose connection to a 1/2 inch male pipe thread (MPT) fitting. The spring guard protects the hose from kinking at the fitting junction, which is a common failure point under repeated flexing. Built from brass, this adapter carries a pressure rating of 125 psi and is rated for a temperature range of -400 to 1200 degrees F, making it suitable for demanding commercial vehicle and industrial air system environments. Installation is performed by licensed or experienced trade technicians working on air brake or pneumatic systems.

This adapter is used in air brake system hose assemblies on commercial trucks, trailers, and related pneumatic equipment. The spring-reinforced hose end is a standard configuration in air brake plumbing where hose flex and vibration are constant factors. The 31/32-20 thread specification ensures correct engagement with compatible hose end fittings. It is categorized under MAF/USA Brass Fittings in the MAF Air Brake section, indicating its intended use in North American commercial vehicle air brake lines.

Installation Notes

Installation should be performed by a qualified technician familiar with air brake system service and applicable DOT regulations. Depressurize the air system fully before removing or installing any fitting. Use appropriate thread sealant compatible with brass fittings and air brake system requirements. Inspect the hose and mating threads for wear or damage before assembly.
