Abstract
A seal for a shaft in a structural body. The seal is configured to surround the shaft within said structural body. The seal has a flange making a gasket seal with the structural body. The seal has at least one portion distorted and stretched into a tapered configuration and into a tension-related sealing association with the shaft. The seal is made of a memory-retainable material. This memory urges the distorted and stretched tapered portion towards its original configuration, thereby enhancing the sealing association with the shaft.
