Flange / Sealing gasket

A flange gasket is usually made of rubber, non-asbestos sheeting or graphite sheeting material. Besides these standard sealing gaskets, Ridderflex also offers gaskets in other materials. These other materials have their own specific properties. We produce your gasket custom-made.

Sealing gaskets in various materials

A sealing gasket can be produced 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 on the agreed delivery times.

In addition to these standard gasket materials, Ridderflex also produces custom gaskets in other materials. These 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.
