ABSTRACT:
A sealing device is disclosed for separating sections inside an elongate hole with at least one duct extending inside and along the hole. The sealing device includes a first portion which is arranged, in use of the sealing device, to surround the duct and fit substantially tightly against the same, and a flexible cup-shaped second portion, which is arranged to surround the first portion and be resilient radially outwards to seal, in use, against the hole. Moreover, a method is disclosed for separating sections in an elongate hole with a duct extending inside and along the hole. A sealing device is slipped onto the duct at the intended level so that the sealing device after installation forms a cup shape around the duct. The duct and the sealing device are inserted into the hole, and the duct and the sealing device are installed at the intended level.
