Cartridge Coupling Elements for Machine Tools
Compact cartridge couplings for cavities in customers’ machines, designed specifically for machine tool requirements.
The coupling elements are equipped with clean-break technology that release a minimum amount of media when disconnected. Operation is versatile thanks to integrated misalignment tolerance during connection and small connection force.
