an underwater component; and an annular lip seal disposed within a bore of the underwater component, wherein the annular lip seal comprises:
a first annular portion having a first seal interface, wherein the first seal interface comprises a first protrusion having a curved surface configured to pivot and/or move along a first sealing surface to maintain a seal during misalignment of the annular lip seal, wherein the first protrusion is the only protrusion of the first annular portion configured to contact the first seal interface;a second annular portion having a second seal interface, wherein the second seal interface comprises at least two second protrusions configured to engage a second sealing surface, wherein each of the at least two second protrusions has an arcuate surface; andan intermediate annular portion connecting first ends of the first and second annular portions about an annular space, wherein second ends of the first and second annular portions are free to move toward and away from one another,wherein a first contact point of the first protrusion along the first sealing interface is positioned axially between respective second contact points of the at least two second protrusions with the second sealing interface. |
