<p>The present invention relates to a sealing device (1) for separating sections inside an elongate hole (2) with at least one duct (5, 6) extending inside and along the hole. The sealing device (1) comprises a first portion (7) which is arranged, in use of the sealing device (1) , to surround the duct (5, 6) and fit substantially tightly against the same, and a flexible cup-shaped second portion (8) , which is arranged to surround the first portion (7) and be resilient radially outwards to seal, in use, against the hole (2) . Moreover, the present invention relates to a method of separating sections in an elongate hole (2) with a duct (4, 5) extending inside and along the hole (2) . A sealing device (1) is slipped onto the duct (5, 6) at the intended level so that the sealing device (1) after installation forms a cup shape (8) around the duct (5, 6) . The duct (5, 6) and the sealing device (1) are inserted into the hole (2) , and the duct (5, 6) and the sealing device (1) are installed at the intended level.</p> |
