| 摘要 |
The invention concerns a sealing arrangement for sealing conduits for gaseous or fluid agents, including a closable housing which fits sleeve-like around the conduit and a sealing member which comprises elastomer material, is arranged in the housing in an annular configuration and hag an annular bead which projects towards the wall of the conduit and has a sealing surface which can be applied against the wall . According to the invention the sealing member (8) has an annular gap (13) which subdivides the annular bead (12) in the axial direction into a first radial bead portion (14) at the inward side of the seal and a second radial bead portion (18) at the outward side of the seal, wherein the gap (13) extends from the sealing surface (15) into the annular bead (12) at such an inclination that an acute-angled sealing lip (21) is formed on the second radial bead portion (18) adjoining the gap (13). At the inward side of the seal the first radial bead (14) can have an axial annular groove in the form of an undercut configuration (16) which on the radial bead portion (14) forms an acute-angled sealing lip (17) which is directed inwardly of the seal.
