Our Industrial Interchange quick couplings have been designed for superior performance. These manual connect couplings are made from solid brass and steel bar stock. Stainless steel balls and springs maximize corrosion resistance. A tubular valve is standard for all body sizes for improved flow. Plugs are machined from solid steel and brass. Steel plugs are hardened and zinc plated to provide maximum service life. This series conforms to the MIL-4109C Interchange Standard. Note: Couplers designated with suffix 'B' have brass valves.
