This Parker 8-8 B2HF-SS barbed tube connector is made of type 316 stainless steel and has a 1/2" barbed connection on one end and a 1/2" male NPT threaded connection on the other to connect a tube or a hose to a female NPT threaded connection. This adapter (also called a connector) is made of type 316 stainless steel for more corrosion resistance than type 304 stainless steel. The barbed connection creates a tight seal on a tube or hose, and the male National Pipe Taper (NPT) threaded end connects with a female NPT threaded connection. The integral 7/8" hex nut provides a wrench grip to tighten the fitting. This barbed tube connector is suitable for use in process, power, environmental, and instrumentation systems in high pressure, vacuum, and vibration 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.Parker Hannifin manufactures electromechanical, hydraulic, and pneumatic motion technologies and systems for fluid handling, filtration, sealing and shielding, climate control, process control, and aerospace applications. The company, founded in 1918, is headquartered in Cleveland, OH.
