Abstract—High or ultrahigh vacuum must be provided in new accelerating facilities with wide-aperture vacuum systems, such as FAIR (Darmstadt, Germany) and NICA (Dubna, Russia). One of the problems encountered while designing such systems is the selection of vacuum-tight connections and gasket types. The use of an ISO-K flange with a spring metallic C-shaped seal is considered the most promising possible variant of a detachable vacuum joint in comparison with the COF, ConFlat, or flat VATSeal flanges.
