Abstract
Seal assembly designs for extreme temperatures that include material and structural designs to counteract sealing component shrinkage or expansion caused by thermal expansion or contraction. Provisions can be included to increase sealing stress along the outer seal lip of the seal assembly for low temperature applications where shrinkage can be an issue and to increase sealing stress along the inner seal lip of the seal assembly for high temperature applications where expansion can be an issue.
