This ignition sleeve O-ring serves as a seal between ignition components in specific Citroën vehicles. The ring prevents leakage of gases and fluids and supports stable operation of the ignition system. The material is suitable for engine temperature ranges and contact with oil and fuel. The O-ring has a round cross section with an outside diameter of about 26 millimetres and a profile height of about 4 millimetres. The dimensions match applications in the ignition assembly of older passenger cars and light commercial vehicles of this brand.
