Abstract
A lubricator for a well system comprises at least one piston and at least one piston plug. The at least one piston is axially slidable within the lubricator along a lubricator axis. The at least one piston comprises a piston alignment contour of a surface of the at least one piston. The at least one piston plug is configured to limit an extent of axial displacement of the at least one piston, and comprises a piston plug alignment contour of a surface of the piston plug. The piston alignment contour and the piston plug alignment contour are configured to mate and automatically circumferentially align the at least one piston and the at least one piston plug about the axis upon travel of the at least one piston along the axis toward the at least one piston plug.
