This standard specifies the dimensions of quick -release couplings of the clamped type as used in vacuum technology, as well as those of the“O" rings and their carriers which are associated with these couplings to ensure vacuum tightness.
Note: The dimensions retained for the coupling diameter ensure compatibility of the quick-release coupling with the corresponding vacuum flanges which are standardized in ISO 1609, Vacuum flange- Dimensions.
