- General application area, provided that chemical compatibility conditions and known installation principles are applied.
- Maximum performance is ensured by adhering to the appropriate technical values in connection design and gasket installation. It is recommended to seek consultancy services.
- Limited application area. Technical consultancy is mandatory.
- In a known application, the best method to determine gasket compatibility is by using the P-T diagram. The highest values of P-T can be misleading. Maximum temperature and maximum pressure should not be used simultaneously. Maximum values are provided purely for indicative purposes. These values are related both to the gasket material properties and to the operating conditions. It is recommended to use the P-T diagram when selecting a gasket.
