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.
Why Is Gas Approval So Important?
Gas installations operate under pressure and require materials that maintain tightness for many years. A standard gasket sheet is not always suitable for such applications.
A gasket intended for gas should have appropriate tests and certificates confirming its suitability for use with natural gas and other gaseous media.
This gives the user confidence that the material meets safety and tightness requirements.
GAMBIT AF-300 – Proven Material for Gas Installations
One of the most popular materials is GAMBIT AF-300.
Main advantages:
✅ approval for gas installations,
✅ very good tightness,
✅ resistance to natural gas, water, steam and many chemical substances,
✅ wide range of industrial applications.
AF-300 has been one of the materials most frequently selected by POLBERIS customers for many years.
TEMASIL HT – High Quality and DVGW Certificate
Another very popular solution is TEMASIL HT.
Main advantages:
✅ DVGW certificate approving the material for gas applications,
✅ very high gas tightness,
✅ good temperature resistance,
✅ can also be used in steam installations.
This material is often selected by customers who expect high reliability and confirmed technical parameters.
Are GAMBIT AF-300 and TEMASIL HT the Only Materials Suitable for Gas?
No.
There are many manufacturers of gasket sheets on the market that have approvals for use with gas.
Therefore, you should always check:
-
whether the specific material has a gas certificate,
-
the manufacturer's technical documentation,
-
operating temperature range,
-
allowable pressure,
-
compatibility with the medium.
It should not be assumed that every aramid or asbestos-free sheet is automatically suitable for gas installations.
How to Select the Right Gasket?
Before purchasing, it is worth preparing some information:
-
type of medium,
-
operating temperature,
-
operating pressure,
-
flange type,
-
flange standard (EN 1092-1, ASME B16.5, etc.),
-
gasket diameter and thickness.
Based on this information, a material can be selected that ensures appropriate tightness and a long service life of the installation.
