Hermetic Products

BG manufactures products for use in pressure vessels (high pressure and vacuum applications). BG’s hermetic products use “hard-seal” methods such a molten glass, epoxy, and crush metal sealing to achieve a permanent pressure-tight barrier. Most commonly these methods are used to achieve ceramic-to-metal seals.
