Claim:
1. A slide ring seal, comprising a sealing element and a counter ring, the counter ring having a radial leg configured as a sliding region and having an axial leg configured to seat the sealing element, the sealing element comprising: a main body; a leg projecting in a first axial direction from a first side of the main body; and a plurality of projections projecting in a second axial direction opposite the first axial direction from a second side of the main body; and wherein said leg projects toward a first end of the main body, the leg having a first surface seating against the radial leg of the counter ring, said first surface having a corrugated profile, the leg having a second surface that is radially opposite the first surface and that adjoins said first end of the main body; wherein the second surface forms a static seal with a housing element external to the sealing element, said second surface having an irregular shape comprising protrusions when in an uncompressed state; and wherein the plurality of projections projecting from the second side of the main body project toward a second end of the main body, said plurality of projections being configured as an anti-rotation lock for the slide ring seal; and wherein said plurality of projections contact said axial leg and a distal end of said axial leg extends beyond a distal end of said projections; and wherein the axial leg has an outer circumferential surface and a inner circumferential surface connected by a curved circumferential surface, and recesses are formed in the axial leg and extend radially inward from the outer circumferential surface so that the curved circumferential surface adjacent the inner circumferential surface is continuous.
