Date Sep. 25, 1986.A sealing bush for a moving part has a packing made up of two concentric layers which are bonded to one another. The outer layer consists of a material such as graphite having good resilience. The inner layer, on the other hand, consists of a material such as sealing cord having a coefficient of friction with the moving part which is lower than the coefficient of friction between the moving part and the outer layer. The outer layer bears against the inner layer.
