Improved hermetic seals for casing structures, particularly applicable for insulating-casing structures utilized in connection with gas-type piston-flow circuit-interrupters, are provided including end metallic closure-plate members, which are hermetically sealed in a gas-tight manner to the ends of generally-tubular, or cylindrically-shaped insulating-casing structures, such as porcelain casings, for example. In some embodiments of the invention, an internally-located ring-shaped, mounting-flange member, or adapter ring, is secured, as by a cemented, or babbitted construction, to the inner internal end surface of the insulating-casing structure, and suitable hermetic sealing means are provided for attaching the metallic end closure plate member to this internally-disposed supporting-flange, or adapter member. In other embodiments of the invention, there is provided an externally-located supporting ring-shaped flange-member cemented, or babbitted to an end portion externally of the tubular insulating casing member, and in this particular instance, the end metallic closure plate member may be secured, as by a bolted connection, to such externally-disposed flange-member, with, preferably, a gasket and a solder-sealed ring-shaped mounting member, the latter being affixed, as by a soldered connection, to such end metallic closure-plate member.
