Abstract
A tool for testing pressure in a wellhead, having a stem for insertion in the wellhead. the stem having an up position and a down position. The tool further includes an energizing member and an isolation seal, so that when the stem is in the down position, the energizing member energizes the isolation seal so that it seals against the wellhead. In addition, the tool includes a plug adapter surrounding the stem and having a variable inner diameter that selectively seals against the stem, so that when the stem is in the up position the interface between the plug adapter and the stem is sealed, and when the stem is in the down position, the interface between the plug adapter and the stem is not sealed.
