ISO DIS 2861

Description / Abstract: This International 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 flanges - Dimensions.
