How to Choose a Gasket for Gas? Check Whether It Has the Appropriate Approvals

In gas installations, safety is the most important factor. Even the best flange or valve will not ensure tightness if the wrong gasket is used. One of the most frequently asked questions we receive from POLBERIS customers is:

Which gasket should be selected for gas that has the appropriate approvals?

The answer is simple – only materials with the appropriate certificates for use with gas should be selected, e.g. a Gambit AF-300 or Temasil HT gasket.

Which gasket to choose for fuels, crude oil, gasoline and petroleum-based substances

In applications involving the transport, storage and processing of fuels, crude oil, gasoline and petroleum-based substances, the selection of appropriate sealing materials is extremely important. In such environments, the medium often has an aggressive chemical effect, and operating conditions – such as variable pressure, temperature or the presence of hydrocarbons – place high demands on gasket sheets.

In this blog, you will learn which gasket to use for crude oil, gasoline and petroleum-based substances.
