A sealing apparatus for effecting a temporary seal against an elongate object. The object is placed in a chamber( ) and supported between inlet and outlet apertures in the walls of the chamber. A resilient seal ( ) is placed at the point where the object passes through one of the apertures. A piston ( ) is located on the remote side of the seal being operable to compress the seal towards the relevant aperture thereby deforming the seal laterally into contact with the object to seal the periphery of the object. When the piston is released, the seal reverts to its relaxed condition thereby enabling the object to be moved between the two apertures.
