Midland Industries HE68-68 Brass Hose to Mpt Adapter

Product Description

The MIDLAND INDUSTRIES HE68-68 is a brass hose-to-male pipe thread adapter designed to connect a 3/8-inch hose end to a 1/2-inch MPT fitting in air brake and pneumatic plumbing systems. Constructed from brass, this adapter features a 31/32-20 thread form and is rated for operating pressures up to 125 psi. It measures approximately 2.55 inches in height, 1.1 inches in width, and 1 inch in length, and weighs 0.28 pounds. Licensed plumbers, fleet mechanics, and pneumatic system technicians install this fitting when transitioning from hose to threaded pipe connections.

This adapter is suited for air brake system plumbing on commercial vehicles and heavy equipment where a secure, leak-free hose-to-pipe transition is required. Its temperature rating of -400 to 1200 degrees F makes it appropriate for demanding environments with wide thermal variation. It falls within the MAF/USA Brass Fittings line under the Air Brake hose end connector category, making it a recognized component in air brake service and repair work.

Installation Notes

Installation should be performed by a qualified mechanic or pneumatic systems technician. Depressurize the air brake system completely before removing or installing any fittings. Apply thread sealant appropriate for pneumatic service to the MPT threads before assembly. Do not overtighten; brass fittings are subject to thread damage if excessive force is applied.
