CeramTite™ High Pressure Feedthroughs
CeramTite™ feedthroughs consist of a Nickel plated Alumel pin bonded directly to the threaded bolt using our proprietary glass-ceramic sealing process. These hermetically sealed feedthroughs utilize an O-ring crush seal to make the external pressure seal. The hex bolt side is designed to be the high pressure side of the feedthrough. The temperature rating of the assembly is limited by the O-ring material. Viton® is the standard O-ring material used and this material has a high end temperature capability of 205 ºC.

Additional Information

Additional Information

N/A CeramTite™ feedthroughs are typically used for low power or instrumentation applications in pressure vessels or oil systems. 100% of CeramTec’s Ceramaseal® products are helium leak tested to meet or exceed 10-10 atm-cc/sec (He). Custom bolt sizes, pin configurations or sizes are available upon request.
