ABSTRACT:
The present invention is directed to a sealing element which comprises at least a spirally rolled, film-like material made of expanded polytetrafluoroethylene (ePTFE), the sealing element over its cord cross-section having a density gradient which increases, starting from the outer side of the sealing element, in the direction towards the center of its cross-section. Furthermore, the present invention provides a sealing element which has a second annular formation which is connected to the first annular formation by means of a flexible-tube-like intermediate region made of the same film-like material. The two annular formations may also be arranged at a predetermined distance from one another.
