Description & Features

Designed for air brake systems on commercial and fleet vehicles, the 3/8 A.B. Brass Bulkhead Union provides a reliable male-to-male union connection for nylon tubing with 3/8 in. ends on both sides. Constructed from brass and finished with Dura-Kote plating, the fitting offers strong resistance to corrosion in demanding transport and fleet service environments.

Part of the Aeroquip line, this bulkhead union is rated for use down to -40°F and is suitable for air brake applications where temperatures do not exceed +200°F. It is not rated for fuel, water, or oil service. The design meets higher operating pressure thresholds above SAE standards, and the 0.625 in. hex accommodates standard tooling for secure installation through panel or bulkhead surfaces.
