Abstract
A seal system is adapted for use in gas flow systems. The seal system has two seal faces and a longitudinally compressible seal spring-biased between the seal faces. The seal has a bellows configuration and opposite ends in sealing contact with the seal faces, such that at least one end of the seal is free to move relative to the corresponding seal face while maintaining the sealing contact. The seal system is particularly suited for use in sealing an engine to an exhaust member.
