Automotive Interchange couplings
Our Automotive Interchange quick couplers 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.

Universal Quick Couplings
TUniversal couplers are designed to accept the most common styles of 1/4" nipples; Automotive, Industrial, and Aro. These couplers also interchange with the European high-flow style offered by Cejn, OBAC, and Nitto. The design of this coupler combines the easy push-toconnect feature while still maintaining a sleeve coupler profile to prevent accidental disconnection when hoses are dragged. Universal style couplings employ a different valve design than common North American parts that allows much higher air flow rates

Injection Mold Couplings
Injection mold couplings provide quick coupling for cooling and heating hoses used on injection molding equipment. They are machined from solid brass bar stock. Stainless steel balls, retaining ring, and spring provide maximum service life. A high temperature silicone seal is standard. Plugs are machined from solid brass and steel bar stock. Steel plugs are zinc plated for superior corrosion resistance. Mold couplings are usually installed by adding G21B or G2016 hose barb fittings - see Brass Section of this Catalog. Where coupler must be valved, the valve and spring are inserted and retained when the hose barb or other fitting is attached.
