This Dixon D344R brass in-line swivel hose fitting has a barbed shank and a 1/4" male National Pipe Taper (NPT) and a 1/4" female NPT threaded connection. The brass construction provides corrosion resistance, ductility at high temperatures, and low magnetic permeability. This swivel hose fitting has a 150 pounds per square inch (psi) maximum working pressure at 70 degrees F and allows an in-place connection to air supply piping, such as for air tools at a workstation in a fabrication shop.

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.
