An hermetic sealing system for openings in an enclosure. In one form a cover is provided having an edge fitting over a container having a lip with the cover fitting loosely over the lip of the container. A flexible gasket member is provided between the lip of the container and the edge of the cover. A metal band is provided encircling the mating portions of the container and the cover compressing the flexible gasket between such mating portions. A mastic such as a room temperature cure epoxy is forced into the space between the metal band and the container, the mastic also filling the space between the edge of the cover and lip of the container and moving into contact with the flexible gasket. The mastic is then cured, firmly sealing the cover to the container. If desired, the metal band may be treated with a release agent and then removed after the mastic is cured. In another form, a bushing member surrounds an opening in a wall and is bolted to the wall. A channel in the base of the bushing carries a flexible gasket member compressed against the wall member about the opening. A second channel in the base of the bushing is filled with a mastic which when cured seals the bushing to the wall member.
