Abstract / scope
ISO 2861-2:1980 specifies the dimensions of quick-release couplings of the screwed type as used in vacuum technology, as well as those of the “O” rings and the insert which are associated with these tailpieces to ensure coupling tightness.
General information is also included which refers to the clamped quick-release coupling standardized internationally in ISO 2861-1, with which the screwed quick-release coupling specified in ISO 2861-2:1980 is compatible.
