This Dixon BN series brass two-piece adapter has a male NPTF threaded end and a female barbed hose end to connect hose or fittings of different types. This reusable adapter has a barbed end to connect hose to a fitting using the removable threaded sleeve, and the other end has female National Pipe Taper Fine (NPTF) threads to connect to a male NPTF connection for a tighter seal than straight threads. It is made of brass for resistance to corrosion, ductility at high temperatures, and low magnetic permeability with a maximum working pressure of 250 pounds per square inch (psi) at 70 degrees F. This two-piece adapter is recommended for low pressure air hose 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.
