A sealing arrangement, which is particularly suitable for flat flange connections, has an annular, metallic base body (1). Connected to the metallic base body (1) at both sides are soft material supports (2). The base body (1) has ring teeth (3,4) which run around radially at the inside and/or at the outside. The ring teeth (3,4), in the installed state, permit punctiform metallic contact and also have a spring characteristic. The spring characteristic of the ring teeth (3,4) is selected such that, in a first embodiment, after the removal of the seal from the flanges, the tooth height corresponds substantially to the height before the installation. The region of the base body (1) which is covered by the soft material supports (2) also has angular ring teeth (5). Said ring teeth (5) have a spring characteristic, wherein after the removal of the seal, the ring teeth (5) spring back to at least 75% of the original state. In a further embodiment, the ring teeth (5) which are covered by the soft material support (2) are partially plastically deformable. |
