<p>Leakage producing faults in a guide tube of finite length are repaired by encapsulating the guide tube within a sleeve-like member (24) which extends between a wall, from which the guide tube projects, and a housing which passes through the guide tube and extends beyond the end thereof. The sleeve-like member (24) has resilient seals (26,28) at the ends thereof, is pre-loaded to partially compress the seals (26,28) and is shaped so that exposure thereof to a pressurized fluid will result in further compression of the seals (26,28).</p> |
