This Dixon STC Series jump size King combination nipple hose fitting is made of plated steel and connects hose of a different diameter to an NPT female connection. This King combination nipple has a barbed end to create a tight seal on a hose when used with a hose clamp or crimp sleeve or ferrule (not included) and male National Pipe Taper (NPT) threads on the other end to connect to female NPT threaded connections. This fitting connects hoses of two different inside diameters (ID). It is made of plated steel for greater corrosion resistance than unplated steel. It is for low-pressure discharge or suction applications.

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.
