Description
The Mercedes-Benz Sealing Ring A1199970045 is a genuine OEM copper washer precisely engineered to create a tight, leak-free seal in high-pressure systems such as engine oil, transmission, brake, or fuel lines.
Made from high-purity annealed copper, this washer deforms slightly under torque, filling any microscopic gaps between surfaces to prevent fluid leaks.
Whether replacing a drain plug, fuel banjo bolt, or hydraulic fitting, the A1199970045 sealing ring ensures factory-level durability and sealing reliability.
Recommended for use every time a plug or line is removed, it helps maintain the long-term integrity of your Mercedes-Benz fluid systems.
