Abstract
A metal seal flange assembly for a vacuum system is presented. Its metal gasket has a crossectional shape that is an irregular hexagon with two acute angles between the longest side and the second- and third-longest sides, respectively. The longest side of the irregular hexagon is the vertical inner wall of the metal gasket. This design can reduce the normal force required to seal the metal seal flange assembly and reduce the number of bolts needed, enabling use in a limited working space.
