Abstract
Apparatus are provided for an access system for a passage defined in a component. The passage is surrounded by a flange, and the access system comprises a plug adapted to be coupled to the flange of the component to seal the passage. The plug includes a sidewall and an overhang coupled to the sidewall. The overhang is configured to substantially surround at least a portion of the flange and the plug is movable between a first, unsealed position and a second, sealed position upon the application of a force.
