This copper ring for the braking system is used in hydraulic connections on classic vehicles. The 14x18x1.5 mm ring provides a tight seal between brake line and component, so brake fluid remains inside the system. The soft copper adapts to the contact surface and limits leakage. The ring is used during maintenance or replacement of parts in the braking system. Use follows the standard assembly sequence for brake lines with copper sealing rings. The dimensions fit specific connection types as found on certain passenger car models with a similar design of hydraulic brake components and fittings.
