ABSTRACT:
Leakage producing faults in a guide tube of finite length are repaired by encapsulating the guide tube within a sleeve-like member 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 has resilient seals at the ends thereof, is pre-loaded to partially compress the seals and is shaped so that exposure thereof to a pressurized fluid will result in further compression of the seals.
