The pressure/temperature graph shown is 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 2.0 mm:

  • 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. Please call or refer to KLINGERexpert for assistance.
  • In area 3 do not install gaskets in these applications without first referring to KLINGERexpert or contacting KLINGER Thermoseal’s technical support service.
  • There are often strong pressure shocks, particularly in steam applications, that result in damage to the gasket material. A more flexible gasket that withstands greater expansions without rupture is a factor that contributes to a safer, more reliable gasket joint.
