This nylon ring serves as a sealing element for a banjo bolt in the fuel system of a classic Citroën. The part supports a tight connection between fuel line and carburettor and limits fuel leakage. The ring is matched to a specific Citroën model and fits the corresponding banjo bolt dimensions. The nylon material has a stable shape and contributes to an even pressure distribution around the joint. The ring is used during service or overhaul of the carburettor connection and helps maintain the operational reliability of the fuel system during regular use of the vehicle after repair or replacement.
