Annular gasket

摘要

The flat sealing ring (1) for a fluid-tight joint between two surfaces pressed against one another comprises a stiffening ring (3) which is located at the inner and/or outer periphery of the elastically deformable main ring (2). The stiffening ring is less flexible than the main ring in the direction perpendicular to plane of the sealing ring. It also has a smaller height than the maximum dimension of the main ring in this direction.
