In the Vacuum Components industry there can be few more specialized technologies than the production of ceramic-to-metal seals. Ceramic-to-metal sealing, the bonding of ceramics to metals, is fundamental to the manufacturing of thousands of devices used in applications where electricity and optics must interface with high and ultrahigh vacuum environments.

Some of the products available from Insulator Seal include a complete line of thermocouple feedthroughs, single and double-ended multipin instrumentation feedthroughs, an extensive selection of industry standard coaxial instrumentation and power feedthroughs, high frequency RF power feedthroughs with patented cooling geometry, electrical breaks suitable for cryogenic service, VacOptix® patented viewports for deep ultraviolet and far infrared optical applications as well as custom engineered products for exotic or demanding applications.
