# High-temperature sealing

Graphite gaskets, packings, and seals for flanges, furnaces, and equipment operating at high temperature.

Family: Sealing applications

## Processes
- Hot flange sealing
- Furnace sealing

## Challenges
- Elastomer degradation
- Leaks from thermal cycling
- Oxidation

## Advantages
- Thermal range above elastomers
- Specialty gaskets and packings
- Design by process condition

## Limitations
- Oxidation in air at very high temperature
- Chemical compatibility of the medium
- Does not replace mechanical joint design
