Claim 0:
1. A method of sealing an installation hole comprising:
providing an insert which is a sealing 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;
the cylindrical metallic sleeve secured to the core in a position prior to engagement of a male threaded device and prior to the core being retracted into the cylindrical metallic sleeve wherein the cylindrical metallic sleeve is secured to the core with a first end of the core secured to the cylindrical metallic sleeve, the cylindrical metallic sleeve having a second height and a hole defining an inner diameter wherein a maximum diameter of said cylindrical metallic sleeve is less than or equal to a diameter of the installation hole;
a second end of said core having an outer diameter larger than the inner diameter of said hole;
placing the insert in the installation hole which is a cylindrical hole;
pulling said core into said cylindrical metallic sleeve with a male threaded device which is threaded into the threaded hole, the pulling sealing the installation hole wherein, said core exerts an outward force on an inner surface of said cylindrical metallic sleeve to radially expand said cylindrical metallic sleeve;
wherein the insert is installed in the cylindrical hole such that the core is in a position retracted into the sleeve with the threaded hole facing outwards and such that the core exerts outward pressure on an inner surface of the metallic sleeve to force the cylindrical outer surface against the cylindrical hole, wherein the core retracted into the sleeve and seals the hole of the metallic sleeve.
