Scope
ISO 5675:2021 specifies essential interface dimensions and operating requirements for general-purpose hydraulic couplers transmitting hydraulic power from agricultural tractors to agricultural machinery, excluding braking circuits.
Dugong relevance
Where Dugong uses couplers within this scope, the specific coupler can be checked against ISO 5675 documentation or supplier certification.
Wording to use
Prefer “hydraulic couplers conforming to ISO 5675” only when verified. Avoid “ISO hydraulics” as a blanket description because it does not identify what is actually standardized.
