The utility model relates to the technical field of ring groove sealing, and discloses an octagonal metal annular gasket for a ring groove sealing surface flange, which comprises a structure main body, a metal gasket is arranged on the inner side of the structure main body, a limiting groove is arranged in the middle of the outer side of the metal gasket, a wear-resistant sealing ring is plugged in the limiting groove, and the wear-resistant sealing ring is arranged in the limiting groove. And a reinforcing elastic ring is arranged on the inner side of the wear-resistant sealing ring. According to the utility model, the wear-resistant sealing ring is directly sleeved on the outer side of the limiting groove, so that the contact area between the outer side of the metal gasket and the position to be installed is smaller, and the generated wear degree is reduced; the metal gasket and the to-be-installed position are buffered to a certain extent, so that the service life of the metal gasket is longer, only the we
