Ceramaseal® UHV Components

Ceramaseal® products include feedthroughs, multipin connectors, coaxial connectors, thermocouples, isolators, viewports, and vacuum hardware. These components are ideally suited to support optical, gas, liquid, power, instrumentation, and sensing applications. All of these products are built to endure extreme conditions, whether it be an ultra-hign vacuum (UHV) environment, temperatures ranging from cryogenic (4 K) to 450 degree C , pressures in excess of 25,000 psig, corrosive or caustic environments, while maintaining an unsurpassed level of reliability and performance.


Testbourne maintains an extensive stock of precision-engineered hermetic electrical & optical components. If any items are not in stock we will endeavor to offer a fast turnaround with the factory.
