ABSTRACT:
A method and apparatus for the internal or blind side sealing of a small local leak (such as a void in casting). The sealing is accomplished by first drilling a hole in the conduit or container where the leak is located and setting a blind side sealer apparatus in the hole. The device consists of a guide that fits loosely into a drilled hole; a slitted metal conical capping means having an outside diameter approximately the same as the drilled hole diameter; a sleeve; and a retractable stem. The slitted cone is filled with a viscous sealant and the slitted cone part of the sealer assembly is pushed through the hole. Once on the other side of the hole, the slitted cone expands enough to prevent it from backing out. When the stem is pulled outward, the slitted cone is forced against the pipe or container wall, spreading the sealant. The stem then snaps at a necked-down position, signaling completion to the operator.
