Abstract
A seal assembly that is usable with a well includes a metal body that is adapted to expand radially inwardly and radially outwardly in response to the body being longitudinally compressed between compressing surfaces. The metal body includes first and second surfaces that do not conform to the compressing surfaces before longitudinal compression of the body and are adapted to contact the compressing surfaces.
