ABSTRACT:
A seal system for sealing between a pair of members is provided wherein a pair of substantially aligned walls on inner faces of the members have internal frustoconical portions. A metal ring includes a pair of lips with external frustoconical portions which sealingly engage the internal frustoconical portions. The metal ring includes at least one convolution between the lips. The convolution permits axial extension of the metal ring upon application of external pressure to the ring.
