This Dixon SV Series in-line heavy duty, free-turning swivel is made of steel and connects a male NPT threaded connection to a female NPT threaded connection. It has female National Pipe Taper (NPT) threads on one end to connect to a male NPT threaded connection, male NPT threads on the other end to connect to female NPT threaded connections to create a tighter seal than straight threads, and a free-turning swivel to reduce hose kinking. This fitting is made of steel for better weldability and greater rust resistance than wrought iron. It is rated to a working pressure of 250 pounds per square inch (PSI) (17.01 bar) at 70 degrees F with a minimum pressure of 35 psi. This air hose fitting is suitable only for air service applications such as air drills and pavement breakers.
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.
