High Temperature Seals

Hermetic Seals

Our range of high temperature seals are generally employed where extreme fluctuation of temperature occurs, or where temperature is consistent but the environment is harsh.

The most suitable solution for high temperature situations are our ceramic Feedthroughs, which are the superior, high quality solution. They are reliable for applications subject to extreme conditions including low cryogenic temperatures and high temperatures, up to 1100°C. Designs can be complex electronic packages through to simple ceramic based filament holders used in scientific applications. For more detailed information about our Ceramic Seals, click here.

We offer a wide range of materials for body, glass and contact.
