The present invention relates to a gasket (1) comprising a first discrete component and a second discrete component, wherein the first and second components (20) extend along the length of the gasket (1). The second component (20) is arranged ranged relative to the first component (10) so as to separate the first component (10) at least from one of the two sealing surfaces (2, 4). The first component (10) is relatively hard in at least the thickness direction of the gasket (1) and preferably incompressible and the second component (20) is relatively soft in at least the thickness direction of the gasket (1) and compressible. When the gasket is compressed between two flanges (101, 102), there is a limited region of high compression, because the first component (10) increases the pressure by which the second component (20) is compressed between the surfaces of the flanges. This yields a high leak tightness of the sealing at a relatively low force.
