The second seal portion mates with the first retainer portion of the first seal ring, while the first seal portion is in a sealing relation with one component. The second resilient seal ring has a second resilient seal portion, and first and second seal portions. The second resilient seal portion urges a second seal surface of the second seal ring against the first seal surface of the first seal ring, while the second seal portion mates with the second retainer portion of the second seat ring.
