Abstract: The present invention introduces a metal seal flange assembly for a vacuum system. A new designed metal gasket has a crosses-section shape of irregular quadrangle with two sharp angle forms by the longer base and legs. The long base of the irregular quadrangle is the vertical inner wall of the metal gasket. A preferred cross section shape of the metal gasket is trapezoid or isosceles trapezoid. This design can reduce the normal force applied to the metal seal flange assembly and reduce the number of bolts used in a limit working space.

Abstract: A metal gasket has a cross-sectional shape that is a six sided shape that resembles an irregular quadrangle that is substantially isosceles trapezoidal in shape with two sharp angles between the longest side and the second- and third-longest sides, respectively. The longest side of the cross section is the inner wall of the metal gasket.
