<p>An inflatable seal system comprises a longitudinally extending seal cavity 4 and a seal 2 extending longitudinally along the seal cavity 4, the seal 2 being cut to a length appropriate for the seal cavity 4. A connector 46 which communicates the seal with a source of pressurised fluid is provided at one end of the seal. The other end of the seal is closed to prevent escape of fluid therefrom. Also shown is an inflatable seal system in which the seal 2 comprises an inflatable portion 8 and an abutment portion 12 for sealingly abutting against an opposing surface, wherein the inflatable portion 8 remains in the seal cavity 4 when the seal is deflated. <IMAGE></p> |
