Glass-to-metal Seal

Glass-to-metal sealing is traditionally a fusion technique with the glass melted in contact with the metal parts to be joined or sealed to. Glass-to-metal seals are widely employed in the preparation of electrically insulated feedthroughs connectors.

This technology not only can be mechanically strong, also the glass is relatively impervious to gases, it is a good electrical insulator, it is reasonably refractory and the technology is well developed and understood.
Thanks to the glass-metal seals, the insulated feedthroughs connectors have a large list of advantages.
•    Vacuum sealed connectors 1E-8
•    High corrosion resistance
•    Humidity protection
•    Temperatures up to 650ºC
•    High shock and vibration resistance
•    Thermal shock stability and resistance
•    High durability
