This spring ring for the brake hose connection nipple serves as a retaining element between hose and brake line. The component helps limit play and unwanted movement in the connection and supports a stable joint within the brake system. The ring is matched to classic Citroën models with metric threaded connections. It is used during maintenance or overhaul of the hydraulic brake system and fits in combination with the corresponding nipple. The design supports secure positioning of the brake hose under changing operating conditions and contributes to preserving the functional integrity of the brake line interface.
