Abstract: A sealing system, in particular for sealing multiple part exhaust-gas lines for an internal combustion engine, has at least a first flange part (9) and a second flange part (11) guiding a flow of heat (5). The flange parts (9, 11) delimit a receiving space (33) for at least one sealing element (31) between them and adjoin one another. Each flange part forms an outwardly projecting annular flange (13) facing away from the flow of heat (5), and extending transversely with respect to the heat flow. Chambering of the receiving space (33) is formed for the sealing element (31) by an annular groove (45) open at the end face (17) of at least one flange part (11) and recessed axially into said end face (17). At least one covering element (47) is arranged in the annular groove (45) and provides thermal shielding for the sealing element (31) at least on its side facing the end face (17) of the flange part (11).

Abstract: The invention relates to a flat gasket with a gasket sheet having a plurality of passages. The gasket sheet comprises at least one first sheet metal layer which has at least on one side at least one elongate elevation with an elongate base formed out of the sheet metal layer. The base, under maximum stress occurring during installation of the gasket and in machine operation, is stable with respect to the height thereof in at least first longitudinal sections. The flat gasket is particularly useful for cases where machine part sealing surfaces between which the flat gasket is to be inserted do not have the component elasticity required for a reliable seal. The gasket sheet has at least one second sheet metal layer which has a height-elastic bead in the area of the base which, together with the base, forms a thickness-elastic area of the flat gasket.
