A sealing system, particularly useful for packers and anchors, is disclosed. The sealing element or elements are of a nonelastomeric material and are configured with a feature that can add a biasing force on one or both sides of the non-elastomeric sealing element(s) to allow the sealing element(s) to maintain the seal despite temperature or pressure fluctuations in the wellbore. The apparatus allows a packer with a nonelastomeric seal to be set at a broad range of downhole temperatures.
