| General suitability using common installation practices under the condition of chemical compatibility. |
| Max. performance is ensured through appropriate measures for joint design and gasket installation. Consultation is recommended. |
| Limited application area - Technical consultation is mandatory. |
The Pressure - Temperature charts are the most current method of determining the suitability of a gasket material in a known application. Maximum figures for temperature and pressure can be misleading. Max. temperature and max. pressure represent maximum values and should not be used simultaneously. They are given only for guidance, since this max. values depend not only on the type of gasket material but also on the assembly conditions. Use the pressure and temperature graphs to check suitability of chosen gasket material for your application (combination of pressure and temperature).
