Abstract
According to one embodiment, a composite seal may include a first, substantially annular seal element having an upper body portion, a neck portion, and an axial protrusion. The upper body portion includes opposing inclined surfaces extending toward the neck portion defining a first angle. The axial protrusion includes opposing inclined surfaces extending toward an axial end of the axial protrusion defining a second angle, wherein the first angle and the second angle are substantially similar. The composite seal may further include a second, substantially annular seal element having a mouth portion, a neck portion and a recess portion, wherein the axial protrusion is configured to be complementarily engaged with the recess portion in an interlocking manner.
