Open S Steelwrist 192x1250 Green

Standard in brief.

Open-S is a common standard for the hydraulic interface between machine couplers, tiltrotators and/or tools. This definition entails that the quick couplers that follow the standard are compatible between different manufacturers and products. For more technical details, download the Open-S technical specification here.

The interface builds on the established, symmetrical quick coupler standard for excavators (the S Standard) developed by machine suppliers.

Open-S does not define the technical solutions incorporated in quick couplers or products, but rather ensures that the quick couplers from different manufacturers are compatible with one another. Open-S is completely machine and system independent, which means continued freedom of choice to define different functions and additional features in the systems.
