Electrical and optical Ceramaseal® components with ceramic parts such as electrical feedthroughs, NPT feedthroughs, coaxial connectors, isolators, multi-pin connectors, viewports, thermocouples, terminals, and accessories are just some of the specialties of the CeramTec experts in North America.

Hermetic, vacuum-sealed Ceramaseal® products are built to endure extreme conditions. They stand up to ultra-high vacuum (UHV) environments, temperatures ranging from -269°C to 450°C, pressures in excess of 1,700 bar, corrosive or caustic environments, while maintaining an unsurpassed level of reliability and performance – Ceramaseal® products are known around the globe for their reliability. For ceramic-to-metal and glass-to-metal components, and glass-ceramic sealing technology CeramTec offers both standard and custom designs for use in vacuum, ultra-high vacuum, high-pressure, cryogenic, and high-temperature applications.

Ceramaseal® products from CeramTec undergo a 100% helium leak test on a dry leak detector to 1×10-9 atm cc/s He. Products can be tested to 1×10-10 atm cc/s on request. The vacuum-sealed ceramic-to-metal and glass-ceramic-to-metal components are designed for cryogenic applications and can withstand temperatures of up to 450°C with a leak rate of under 1×10-9 atm cc/s Helium; they are also suitable for use with currents of over 1,000 A and voltages exceeding 100 kV.
