Product description

Notes
Further information on request.
Not suitable for striking or pulsating tools!
Description
High-quality, robust and durable, one-hand quick disconnect safety couplings for high flow rates. When it is pressed for the first time, air is relieved from the coupling but the plug in the coupling remains locked. The plug is only disconnected when the pushbutton is pressed for the second time. The dreaded »whiplash effect« is avoided and the risk of injury to the operator virtually eliminated. The safety version conforms to ISO-Standard DIN EN ISO 4414.
Further information
The indicated working pressure refers to the coupling only and is dependent on the selected connection types.
