Made of high-quality, durable materials Suitable for "A" series quick couplings, complete with male and female threads, available in NPT thread sizes. The A-fitting is used for quick connection and disconnection of hydraulic lines. During coupling in the zero or low pressure range, the valves that release or block the flow start automatically. The coupling consists of a coupling plug and a coupling sleeve, which are connected by pushing the sleeve. This ensures a flush connection between the two coupling halves. Use: for agricultural and forestry equipment, such as tractors, trailers, harvesters; Construction equipment and multi-purpose vehicles, such as excavators, skid steer loaders and hydraulics; Mining rigs and industry. If there is pressure in 1 or more hydraulic lines, use appropriate pressure connectors and mining rigs. Brand new and high quality Installation form: change interface Type: Through Model: ISO7241-A Scope of application: agricultural machinery and industrial
