Flange gaskets

Our flange gaskets range varies from industry standards to complete customisation. We supply high-quality gaskets according to DIN, ASA and ANSI sizes. We also produce your gaskets completely custom-made.

Flange gaskets in various materials

We can produce a flange gasket in various materials. The standard gasket materials are rubber, non-asbestos sheeting and graphite sheeting. These materials are always in stock, so we can supply quickly and within the agreed delivery times.

We supply sealing gaskets, square and rectangular gaskets and strips in the following gasket materials:

Standard materials
Other materials
  • Cork/rubber
  • Oil paper
  • Felt
  • Cardboard

The other materials have their own specific properties. For example, a flange gasket of oil paper slightly swells under the influence of oil, which creates the sealing function. Cork rubber has a fine structure, which makes this gasket material particularly dens. If drenched in oil, a felt gasket has a double function: it is both a dust seal and provides lubrication of the underlying bearing.

Gaskets with a large diameter

Do you need a gasket with a large diameter? No problem for us. Our gaskets can be supplied in loose individual segments or ready made in one piece with diameters of dozens of meters. Are you curious about the possibilities? Please contact our sales department.
