This Dixon 4EAF series steel hydraulic water-blast quick connect 1/2" female coupler has a 1/2" – 14 NPTF threaded end, valveless construction, and connects to a hydraulic water-blast quick connect plug. The female National Pipe Thread Taper Fine (NPTF) threaded end connects with male NPTF threads for a leak-tight connection or with male National Pipe Taper (NPT) threads for a leak-resistant connection. The steel body components resist brinelling and internal corrosion, provide better weldability and greater rust resistance than wrought iron, and the valveless construction provides maximum flow with minimum pressure drop. A knurled sleeve with locking pin protects against brinelling and accidental disconnection. This coupler's maximum working pressure (MWP) is 10,000 pounds per square inch (psi) (689.47 bar) at 70 degrees F. It is used for general purpose hydraulic 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.
