A caulk, sealant, or glue tube repair system and apparatus is described. A form-fitting cap, equipped with at least one tip, is disclosed, which is configured to replace the default top and/or tip of a conventional caulk/sealant/glue tube. The apparatus facilitates the effective replacement of the top and nozzle of the tube container such that it may function as-new within a caulk gun. Via replacement of the nozzle/top of the tube container, hardened or dried contents of the container may be removed, providing for continued use of the remaining contents of the tube container. The apparatus is equipped with a nozzle, an air hole, and a tube entry point. The tube entry point is tapered such that it provides a hard seal against the tube container.
