Claim:
A ring-shaped flange gasket produced from a rubbery-elastic material, said flange gasket comprising two rings, each having a ring-shaped reinforcing insert, said rings being formed in a wedge-shaped manner transversely relative to the ring axis and, at sides that face each other, adjoining one another at right angles to the ring axis by means of planar surfaces, wherein the planar surfaces are engaged with one another so as to be rotatable, wherein along at least one circumferential section, each of the ring-shaped reinforcing inserts has a plurality of waves that are defined by a wave profile, wherein the waves each have a wave crest, and wherein the wave crests increase in height in a region of increasing wedge height such that along the at least one circumferential section the height of each wave crest progressively increases in a direction defined by the increasing wedge height.
