CeramTec’s pressure feedthroughs are terminated in NPT (National Pipe Thread) fittings or other threaded fittings to allow for easy bulkhead installation. The NPT (National Pipe Thread) pressure units are designed to be sealed using PTFE tape or other acceptable sealants. All other designs use an O-ring seal.

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.
