The glass frit hermetic vacuum connector, also known as a metal-to-glass feedthrough socket, is formed using high-temperature fusion bonding of metal and borosilicate glass. It achieves permanent hermetic insulation through chemical bonding, eliminating rubber O-rings to prevent aging, outgassing, and leakage. This component is designed for electrical feedthroughs in vacuum chambers and sealed enclosures.
