| Quick-Disconnect Couplings |
|
 |
For quick, easy to handle and safe connection of tools or hoses for compressed air and other fluids |
| |
quick disconnect couplings in different dimensions (according to requirements) are used. |
|
This system consists of coupling and plug, where all connections in one dimensional system are |
| |
interchangeable. Simple pulling-in of the plug connects, removing of the plug by pulling the coupling sleeve back (with automatic locking of the coupling). |

|
|
Mini Quick-Disconnect Couplings of brass MS 58 |
|
2-way shut-off to avoid the escape of medium when disconnecting. Robust, safe and reliable |
|
Attention: Couplings can be connected with non-shut-off plugs DN 5, but shut-off plugs cannot be |
| |
connected with standard couplings DN 5! |
|
Several fields of application, above all for liquid mediums in construction, control technology |

High quality, robust Quick Disconnect Couplings with optimum sealing |
|
New locking-system, extremely easy to connect and disconnect |
|
Lightweight because of plastic compound material – no scratching of sensitive surfaces |
|
Safety-air relief function: First activation of the sleeve in arrow direction 1 causes an air relief from the plug side. Simultaneously the coupling |
| |
closes. With a second activation of the sleeve to the opposite direction safe disconnection of the coupling without pressure. |
|
Connecting similar to all standard quick disconnect couplings |
|
Interchangeable with the “Euro-profile” DN 7,2 resp. DN 7,4 |
