A static sealing arrangement, comprising a strip-shaped seal of elastomeric material pre-installed in a groove formed in a first structural member and having a contact portion which protrudes, when free, and is held tightly pressed against a planar sealing surface of a second structural member is characterized in that the elastomeric material possesses the property of swelling greatly under the influence of the medium to be sealed off and is joined directly to the material of the first structural member by being formed integrally with the same, and the cross sectional profile of the seal is designed to be asymmetrical, having the contact portion offset towards the side facing air of the seal, and the wall of the groove facing the medium projects towards the sealing surface of the second structural member by such a distance, as compared to the wall of the groove which faces air, that the wall facing the medium comes to lie adjacent the sealing surface in the final assembled state of the sealing arrangement.
