  • Alternative metallic seals
    Patent number: 6637750
    Abstract: A metallic sealing element comprises a generally tubular body having first and second opposed ends and a center section which is located between the first and second ends. In use the sealing element is compressible to bring the first and second ends towards one another to cause a center section to bulge transversely and sealingly engage a co-operating sealing surface.
    Type: Grant
