Our couplings for machine tools and industrial plants enable the efficient connection and disconnection of systems, machines, operating units and other devices, and are therefore a prerequisite for the economical and rapid connection of moving and stationary systems with each other. Whether for mobile gas devices, filling containers or a quick-release connection to the compressed air system: wherever plug-in connections are more economical than screw-in connections. The rust-free variants in various stainless steel grades expand the area of application to include corrosive fluids, for example.
