More Information
Summary:This invention deals with improvements in a seal for sealing flanges, covers and other objects, which seal consists of a combination of at least one metal annular packing and one elastic annular packing, one of them being situated concentrically about the other one, the metal packing serving mainly as a sealing member and the elastic packing serving as a backing ring. One of the flanges is provided with a stepped recess by which the position of the seal is fully defined and by which the seal is supported laterally. In case of providing the seal in the form of two mutually spaced concentric metal packings between which the elastic packing is fitted, the stepped recess in the flange possesses an appreciably lower upright edge.
