ISO 5675:2021 specifies the essential interface dimensions and the operating requirements for hydraulic couplers employed to transmit hydraulic power from agricultural tractors to agricultural machinery. It is applicable to couplers used in hydraulic lines other than those used for braking circuits.
NOTE All hydraulic couplers are intended to be connected and disconnected frequently to allow the transfer of machinery from one tractor to another without the use of tools or special devices.
