Made of high quality materials, Suitable for ISO series "A" quick release couplings, complete with male and female threads, available in NPT thread sizes. The quick release ISO A coupling is used for quick connection and disconnection of hydraulic lines. During coupling in the zero or low pressure range, valves that release or block flow automatically . The quick release coupling consists of a coupling plug and a coupling socket, which are connected by pushing the sleeve. This ensures a flush connection between the two coupling halves. Purpose: For agricultural and forestry equipment, such as tractors, trailers, harvesters; Construction equipment and multipurpose vehicles, such as excavators, skid loaders, and hydraulic tools; Mining rigs and industry. If there is pressure in 1 or more hydraulic lines, use suitable under pressure connectors and mining rigs. and high quality Installation form: quick change interface Type: Through Model: ISO7241-A Scope of application: agricultural machinery and industrial equipment Nozzle diameter: 10 (mm) Pressure resistance: 40 (MPa) Thread type: internal thread Specification: NPT1/2, Temperature range: - 30 ° C to+120 ° C Operating pressure: 270 - 350 bar (depending on size) Colour:silver Material:Metal Package Contents: 5 set x Quick Release Fitting Only the above package content, other products are not included.
