Made of high quality materials, Suitable for series "A" quick release couplings, complete with male and female threads, available in NPT thread sizes. The quick release 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 will automatically start. 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 , 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. new 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: 1 set x Quick Release Fitting Only the above package content, other products are not included.
