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.
