Abstract:
A method of liquid tight sealing a space between a laterally closed opening (2) in a wall or similar structure and an object (3) having a diameter smaller than the opening (2) and arranged to extend through the opening, comprising the steps of forming at least one sealing element (6) comprising an elastic sealing element (6) held in a compressed state by an enclosing member, inserting the sealing element and enclosing member in an annular form in the opening (2), inserting the object (3) into the annular form of the sealing element so that the sealing element (6) in the compressed state does not seal an open annular space (4) between the object (3) and the opening (2), releasing the sealing element from the compressed state, by destroying the enclosing member, into an expanded state and providing a liquid tight seal by the sealing element of the open annular space between the opening (2) and the object (3).
