Industrial Gas application
Global region
Danfoss Hansen LF series is a specific coupling made for
industrial applications using SF6 gas. Its design allows a
perfect sealing over several decades and an extremely
limited permeation of media into the atmosphere during
connection and disconnection, in order to limit global
warming. The coupling has a dual O-ring design and dust
caps ensuring tight sealing while it is disconnected
