A seal assembly includes a first plate or member having a recess with a bottom mating surface which receives sealing ring therein and a second plate or member having a sealing surface for contacting a metallic sealing ring. First and second plates or members are coupled together by a plurality of fasteners or bolts. By tightening the fasteners the sealing ring is loaded, and thus, compressed to plastically deform and create an annular seal between the first and second members. Metallic sealing ring has a first annular sealing surface, a second annular sealing surface, an annular inner surface and an annular outer surface. The first annular sealing surface faces in a first axial direction to contact sealing surface of first member for creating a first annular sealing dam therebetween. The second annular sealing surface faces in a second axial direction, which is opposite to the first axial direction of the annular sealing surface, to contact sealing surface of second member for creating a second annular sealing dam therebetween. Preferably, the first and second annular sealing surfaces are substantially flat surfaces which are parallel to one another. An annular column section is formed between the first and second annular surfaces. The minimum radial width of the annular column determines the force necessary to deform the sealing ring to its sealing position. A pair of beam sections extend substantially perpendicular to the column section to create the sealing surfaces. At least one brace extends diagonally between the column section and one of the between sections to obtain proper sealing during compression of the sealing ring.

[ What is claimed is:] [1.] A metallic sealing ring comprising:a first annular beam section with a first annular sealing surface facing in a first axial direction to contact a first member for creating a first annular sealing dam therebetween;a second annular beam section with a second annular sealing surface facing in a second axial direction, which is opposite to said first axial direction, to contact a second member for creating a second annular sealing dam therebetween, said first and second annular sealing surfaces being substantially parallel to each other;an annular inner surface extending between said first and second sealing surfaces to form a central passageway; andan annular outer surface extending between said first and second sealing surfaces and spaced from said annular inner surface to form an annular column section of material extending between said first and second sealing surfaces and substantially perpendicular thereto,one of said annular inner and outer surfaces having an annular recess extending in a substantially radial direction to at least partly define an effective minimum width of said annular column section, said annular recess being configured to form a first diagonal brace section extending from said annular column section to said first beam section to control buckling of said first beam section and column section under axial compression of said sealing ring.
