Abstract: A sealing and gripping element for an expandable downhole tool features a ring supporting a sealing material with radially extending rings into the sealing material during run in. Expansion of the underlying ring brings the sealing material into contact with the surrounding tubular. It also forces the radially extending rings through the sealing material and into contact with the surrounding tubular. As a result the tips of the extending rings are blunted to create metal to metal seals on the surrounding tubular. Hardened inserts are also located within the sealing material for run in. Upon expansion of the underlying base ring, the inserts break through the sealing material and penetrate the surrounding tubular to enhance grip when high differential pressures are encountered.
