Abstract
A wellbore system includes a first wellbore component having a tapered interior diameter including a first sealing location and a second sealing location. The wellbore system also includes a second wellbore component with a first flexible seal leg configured to engage the first sealing location, a second flexible seal leg configured to engage the second sealing location, and a slot extending radially into a body of the second wellbore component, the slot forming at least a portion of the first flexible seal leg. The second wellbore component, responsive to a rotational force, is driven into the tapered interior diameter such that the first flexible seal leg forms a first seal at the first sealing location and the second flexible seal leg forms a second seal at the second sealing location.
