The subject of the present invention is a ring seal preventing the seal from sliding and/or tilting when tightened. For this purpose, the invention proposes a seal (10) having an axis of revolution (R) and a median transverse axis (T), and comprising, in cross section, a general D shape defined by a wall (11) forming the back of the D, a wall (12) forming the belly of the D, and two side walls (13). The seal has a height (H) and a thickness (E), the ratio (E/H) of the thickness (E) over the height (H) being between 0.7 and 0.85, preferably 0.8. The back wall (11) comprises, in the uncompressed state, a concave face defining a hollow (11a) between two crowns (14), the hollow having a height (h) of between 50% and 60% of the height (H) of the seal, and a depth (p) of between 4% and 8% of the thickness (E) of the seal.
