ABSTRACT:
The invention concerns a sealing connection, based on a flat gasket of rectangular cross section, for the static sealing of construction elements. The shapes of the sealing surfaces according to the invention lead to a disc-spring-like bending of the gasket, superposed by a compressing deformation, by which an outstanding tightness even at lowest pressing forces is guaranteed. With that the application spectrum reaches from ultra high vacuum to high pressure, and from cryogenic to high temperatures.
