The sealing bead is vertically moveable relative to the gasket body and has a first segment which projects above the main body and a second segment which is in line with the first segment and which is spaced inwardly of the main body. Integral reduced thickness cantilever sections join the sealing beads to the main body and cooperate with the beads to provide restorative energy under loading.
