Pressure-Temperature Diagram

The areas of the P-T diagram:

In area one, the gasket material is normally suitable subject to chemical compatibiliy
In area two, the gasket may be suitable but technical evaluation is recommended.
In area three, do not install the gasket without a technical evaluation.

Note: maximum temperature and pressure should not be used at the same time. All value are dependnet on the application. Please see the datasheet below.
