Technique

This single-hand coupling with hexagonal coding is used to prevent a mix-up of different media. Locking elements are 5 balls that are locked by a spring-loaded release sleeve. The system is secured against unintentional opening by a locknut.
Separation of plug connector and coupling is started by loosening the locknut with subsequent movement of the release sleeve towards the connection.

Please note that this hexagonal coded coupling can just be used in combination with a special plug pug.

Areas of application

Pressure range

The coupling can be statically loaded up to 35 bar without pulsation.
