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.

Apparatus for establishing a fluid-tight seal about a first tubular member which extends outwardly from a surface, the tubular member having an axis, said apparatus comprising: tubular sleeve means, said sleeve means having an axis and a first outwardly diverging end portion, said sleeve means having a second end portion oppositely disposed with respect to said first end portion; first annular seal means, said first seal means being mounted on said sleeve means first end portion, said first seal means being positioned so that a surface thereof will face in a first direction and will be in contact with the surface from which the first tubular member extends when said sleeve means is located coaxially with the first tubular member; second annular seal means, said second seal means being mounted on said sleeve means second end portion, said second seal means being positioned so that a surface thereof will face in second direction which is different than said first direction, said second direction being generally toward the axis of said sleeve means; means for delivering a compressive force to said second seal means; and pre-loading means, said pre-loading means being mechanically coupled to said delivering means and generating a force which is coupled to said sleeve means via said delivering means, said first and second seal means being biased by the force generated by said pre-loading means and being further compressed in response to the immersion of said sleeve means in a pressurized fluid.
