In fluid machines frequently gaps between movable (1) and stationary (2) structural parts have be sealed off. Frequently so-called labyrinth packings are used, whereby sealing strips (5) brush against the opposite structural part. The aim of the invention is to provide an improved system. To this end, a brush layer (7) is configured as a porous coating that can be detached from the opposite structural part (1,2). The inventive system can be advantageously used in virtually any fluid machines.
