Pressure/Temperature Graphs
The pressure/temperature graphs shown are the most current method of determining the suitability of a gasket material in a known environment. However, chemical compatibility must also be considered.
pT diagram for thickness 1/16?:
Gases & Steam
Liquids
In area 1 the gasket material is suitable using common installment practices subject to chemical compatibility
In area 2 appropriate measures are necessary for installation of the gasket to ensure maximum performance.
In area 3 do not install gaskets in these applications without first contacting APG for technical support service.
