*Temperature and pressure represent maximum values and should not be simultaneously.  They are given as guidance, since they depend not only on the type of gasket material but also on the assembly conditions.  Very important factors are: thickness of material, nature of service medium and type of flange and surface stress.  Steam application requires special consideration.
