Sealing discs are used for the sealing of thermocouples in the flange nozzle.

They delay corrosion of the support tube and flange by aggressive process gases and thus extend the service life of the thermocouple.

Due to the special combination of hard and soft materials, the sealing discs are designed for harsh operating conditions, such as those that can occur in sulphur recovery plants.
