This O-ring for the clutch cylinder is suitable for use in hydraulic clutch systems of Citroën DS and SM. The ring provides a reliable seal between the cylinder and adjacent components. The elastomer material limits fluid loss and helps maintain working pressure inside the system. The dimensions match the design of the clutch cylinder and fit the size of the piston and cylinder wall. This component supports stable clutch operation and reduces wear on moving parts. It is used during maintenance, overhaul or repair of the hydraulic clutch section.
