WASHER FOR WATER DRAIN PLUG

This water drain plug ring provides a seal when draining coolant from the engine block or cooling system. The ring fits specific Citroën models and is placed between drain plug and housing. The material limits leakage and supports a stable seal at operating temperatures. The fixed shape and dimensions match the related drain connection and allow use as a replacement part during service or repair. It is used in the cooling circuit at drain points that require periodic opening. The ring supports a constant coolant level and helps prevent unintended loss of fluid during and after draining.
