These Ceramaseal® components are usually used in pressure vessels or industrial environments. High vacuum applications are also common but note that the use of threaded connections in a vacuum system should be minimized. The small spaces between the threads can cause virtual leaks.
CeramTec has been designing and manufacturing high pressure, high-reliability, ceramic-to-metal assemblies for more than 55 years.
The pressure feedthroughs in this section show capability in design for pressures up to 25,000 psig. In every design, the ceramic used is high-grade alumina or glass-ceramic, the NPT mounting members are 304 or 316 stainless steel and the ceramic-metal braze materials are silver, silver-copper or copper.
