Abstract

A sealing system (1) comprising an at least substantially cylindrical tube (2) and at least two sealing collars (4) at least partially made of an elastic material, which are arranged round the tube in spaced-apart relationship for sealing confinement by collaring of the tube in a bushing (3) which is co-axial with said tube, a special feature being the fact that the spacing (a) between the sealing collars is less than 25 mm, said sealing collars comprising an expandable material, in such an amount and of such a composition that the sealing collars will expand in the case of a fire, in such a manner that they will become wedged in the bushing.

1. 1. A sealing system comprising an at least substantially cylindrical tube and at least two sealing collars at least partially made of an elastic material, which are arranged round the tube in spaced-apart relationship for sealing confinement by collaring of the tube in a bushing which is co-axial with said tube, characterized in that the spacing between the sealing collars is less than 25 mm, with said sealing collars comprising an expandable material, in such an amount and of such a composition that the sealing collars will expand in the case of a fire, in such a manner that they will become wedged in the bushing.
