This Dixon DC series stainless 303 Air Chief industrial interchange quick-connect automatic air hose coupler has a male NPT threaded end, and connects a hose to an Air Chief industrial interchange quick connect plug. The male National Pipe Thread Taper (NPT) threaded end connects to female NPT-threaded connections. Stainless steel 303 provides better machining characteristics than stainless steel 316. The coupler meets MIL-C-4109F/A-A-59439 specifications for quick-disconnect coupling halves for hoses and portable pneumatic tools. 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. 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.
