A sealing ring for the gearbox of a Citroën DS is a crucial component that ensures a hermetic seal within the system. It prevents the leakage of fluids such as transmission oil, which is essential for maintaining the performance and longevity of the gearbox. The ring is made from high-quality materials resisting pressure and temperature fluctuations. Suitable for applications in classic Citroën DS models, it helps maintain the integrity and efficiency of the transmission. A properly functioning sealing ring is vital for smooth shifting and the overall driving experience of the vehicle.
