CRANKCASE STOP RING

This crankcase sealing ring is used in the lubrication system of selected Citroën engines. The ring provides a dependable seal between the crankcase and adjacent components. This limits oil leakage and supports stable engine operation. The part fits specific engine versions with matching dimensions. The ring has a flat design with defined inner diameter, outer diameter and thickness. This geometry enables a secure fit in the assigned groove or housing. The material is chosen for continuous contact with engine oil and for exposure to operating temperatures. The ring serves as a passive sealing element without moving parts.
