The invention relates to a flexible seal (1) which is of tubular design and is distinguished, in particular, by permeation-tightness due to the matching of a gas filling in the interior (2) of the seal (1) to the material of the seal (1). The invention also relates to annular seals (1), the interior (2) of which is connected via corresponding holes (3) to the pressure conditions of the container (6) to be sealed off. <IMAGE>
