This Dixon DCP series stainless steel 303 Air Chief industrial interchange quick-connect air hose plug has a female NPT threaded end, valveless construction, shuts off when disconnected, and connects a hose to an Air Chief industrial interchange quick connect plug for air service only. The female National Pipe Taper (NPT) threaded connection end connects with male NPT connections. Stainless steel 303 provides better machining characteristics than stainless steel 316, and valveless construction allows flow when the plug is disconnected. This plug'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 plug meets MIL-C-4109F/A-A-59439 specifications for quick-disconnect coupling halves for hoses and portable pneumatic tools. This air service only plug 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.
