Abstract
A technique for maintaining pressure integrity within a submersible system. The system utilizes a pressure housing with an internal component, such as a valve. The internal component is actuated by an external actuator via an actuator stem. A seal region is positioned to interact with the stem, such that the interior of the pressure housing is sealed and pressure integrity is maintained upon retraction of the stem from engagement with the internal component.
