This Dixon DC series stainless steel 303 Air Chief industrial interchange quick-connect semi-automatic air hose coupler has a female NPT threaded end, shuts off when disconnected, and connects a hose to an Air Chief industrial interchange quick connect plug. The female National Pipe Thread Taper (NPT) threads connect to male 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 coupler'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 semi-automatic coupler has a pull sleeve 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.
