This Dixon DCB series brass Air Chief industrial interchange quick-connect automatic air hose coupler has a barbed hose ID end, shuts off when disconnected, , and connects a hose to an Air Chief industrial interchange quick connect plug. The barbed hose ID connection fits inside the hose, has a greater hold than non-barbed connections. Brass provides corrosion resistance, ductility at high temperatures, and low magnetic permeability. This fitting's maximum working pressure (MWP) is 300 pounds per square inch (psi) (20.41 bar) in a temperature range from -40 to +250 degrees F (-40 to +121.11 degrees C). This automatic coupler allows one handed, push-to-connect operation and shuts off when disconnected. The coupler meets MIL-C-4109F/A-A-59439 specifications for quick-disconnect coupling halves for hoses and portable pneumatic tools. This air service only coupler is used for applications such as pneumatic tools, tire inflation, and general purpose air handling in industrial operations.

Hose fittings connect, control, change the direction of, and terminate the flow in piping and hose systems. They are made of brass, stainless steel, galvanized steel, and other materials that resist corrosion, pressure, and wear. Hose fittings have various types of connections, including threaded, barbed, push-to-connect, dry disconnect, and others including those based on internationally-accepted specifications. Hose fittings are used in systems such as air compressors, automatic manufacturing operations, aircraft controls, and tire installation in industries including agriculture, mining, road construction, firefighting, and aviation.
Dixon Valve & Coupling Company manufactures pipe and hose fittings and accessories. The company, founded in 1916, is based in Chestertown, Maryland.
