This Dixon KHN331 King adapter has a 3/8" barbed hose shank at one end and a 3/8" male National Pipe Taper (NPT) threaded connection on the other. The plated steel construction provides strength and durability. The barbed shank end of the fitting is intended for use with a single compression clamp (not included) and this fitting is suitable for low-pressure water discharge and suction service, such as in road construction.

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.
