Abstract:
1. A sealing system, comprising: a component to be sealed having a longitudinal axis, a radially extending flange, an axially facing contact surface on said flange extending radially relative to said longitudinal axis, and an enclosure on an outer peripheral edge of said flange and protruding axially parallel to said longitudinal axis from said contact surface, said enclosure having an undercut opening radially inwardly toward said longitudinal axis and being closed in axial directions of said longitudinal axis; and a unitary, one-piece gasket forming an axial seal on said component surrounding said longitudinal axis and engaging said contact surface, said gasket having first bead and second beads as material parts thereof, said second bead being concentric with said first bead relative to said longitudinal axis and being smaller than said first bead in length and width, said first bead being movable between an undeformed state in which said first bead projects in an axial direction with a first radial distance of an edge area of said gasket from said longitudinal axis and a deformed state in which said first bead is pressed fiat toward said contact surface with said edge area at a second radial distance from said longitudinal axis, said second radial distance being greater than said first radial distance such that said edge area is outside said undercut in said undeformed state to allow mounting of said gasket on said component and is engaged in said undercut in said deformed state to hold said gasket captively on said component against axial disengagement from said component.
