COPPER RING CYL.HEAD NUT

The copper cylinder head nut ring is an essential component for Citroën models such as the 11CV, 15CV, and HY. It ensures a proper seal and attachment of the cylinder head to the engine, preventing leakage of combustion gases and coolant, which allows the engine to operate efficiently. The use of copper gives this ring excellent thermal and electrical conductive properties, providing durability under extreme temperature variations. It is a crucial spare part for the restoration and maintenance of classic Citroëns, ensuring that these vintage vehicles remain safe and reliable on the road.
