DN20 Quick Disconnect Coupling- for easy coupling and

For easy coupling and uncoupling of hoses. 3-1121-R003 The quick disconnect coupling is very useful in all fields of application where hoses have to be frequently loosened and reconnected e. g. during final tests of completely mounted GIS fields. Thanks to the clamp lock, the DN20 hoses can easily be connected without any loss of SF 6 gas. Therefore, the handling times in GIS production are shortened and productivity is increased considerably.Get price
