Abstract

1357090 Seals FORENADE FABRIKSVERKEN 14 March 1973 12360/73 Heading F2B A sealing arrangement for a piston-rod 2 includes a polymeric sealing ring 6, a metal support ring 7 and elastically deformable means 8 engaging the rings 6, 7, said rings being in mutual contact at corresponding frusto-conical surfaces. The ring 6 may be of P.T.F.E., and the ring 7 of steel.
