Brake Fluid Reservoir Grommet / Master Cylinder Plug - Replaces 113611817A
This brake fluid reservoir grommet seals the connection between the brake fluid reservoir and the master cylinder, preventing leaks and maintaining proper hydraulic pressure. It is a direct replacement for the original plug and fits a wide range of classic air-cooled models from 1967 to 1979. The grommet installs into the top of the master cylinder and secures the metal or plastic reservoir feed tube to create a tight, reliable seal.
