Abstract
A system for pressure testing the seals and fittings associated with at least one communication line (26) passing through a well tool mandrel (12), each communication line housed within a communication line conduit (16) defined through the well tool and sealingly engaged to each end of its corresponding communication line conduit by way of a fitting (53) and the fittings also sealingly engaged to the communication line conduit. The system generally comprises a testing conduit (34) and testing passageway system (47) defined in the well tool mandrel. A testing plug (44) provides fluid communication between a pressure testing source and the testing passageway system. Pressurized fluid is guided from the testing plug, through the testing passageway system, into the communication line conduits, and into contact with the fittings and seals associated with each of the communication line conduits. Leaks indicate the presence of a faulty engagement of the fittings or seals associated with the communication line conduits.
