SEALING PART

摘要

The invention concerns a sealing part (1) for sealing an optical fibre coupling bush (22) in a fluidtight and dirt-proof manner. The sealing part (1) bears a central sealing element (4) and a sleeve (6) coaxially surrounding the latter. The end-face bevel (5) of the sealing element is adapted in planar manner to the end-face edge (23) of the coupling bush (22). When pressure (A) is suitably applied, the sealing element (4) is urged against the bush (22) and seals the latter. The sleeve (6) embraces the outer surface (24) of the bush (22) in a firmly adherent manner, secures the sealing part (1) in a selfcontained rack (21) and seals the bush (22) externally.
