ABSTRACT:
In a high-vacuum closure, a metallic sealing ring is positioned between a first and a second sealing surface. The sealing surfaces are each formed of a metallic surface of revolution and are coaxially arranged. When the sealing surfaces are moved between the open and closed positions, the sealing ring rolls on the sealing surfaces. The sealing ring is shrunk on one of the sealing surfaces for securing it in place.
