Claim 10:
11. A method of sealing a hole comprising:
providing a block having an outer surface with a cylindrical hole therein;
providing an insert, the insert comprising: a core having a height and a tapered outer wall; a threaded hole located in said core, a depth of said threaded hole less than the height; a metallic sleeve having a hole and a cylindrical outer surface, said core held to the metallic sleeve such that a first end of the core and the sleeve are held together prior to a male threaded device engaging the threaded hole;
installing the insert in the cylindrical hole to seal the cylindrical hole such that the core is in a position retracted into the sleeve with the threaded hole facing outwards and accessible from outside the hole wherein the core exerts outward pressure on an inner surface of the metallic sleeve to force the cylindrical outer surface to seal against the cylindrical hole, wherein the core retracted into the sleeve by engagement of a male threaded device which pulls the core into the sleeve to seal the cylindrical hole;
wherein the cylindrical hole is sealed with the threaded hole free from engagement with a male threaded device after installation of the insert in the cylindrical hole.
