Genuine Mercedes 110-987-09-44 64 Rubber Expansion Plug for Windshield Washer Reservoir

The Genuine Mercedes-Benz 110-987-09-44 64 rubber expansion plug is an OEM replacement part designed to seal openings in windshield washer fluid reservoirs. This plug is commonly used to close unused pump openings when headlight washer systems are not equipped on the vehicle.

Key Features:

• Genuine Mercedes-Benz OEM part ensures proper fit and durability
• High-quality rubber construction resists deterioration from washer fluid exposure
• Expansion design creates a secure, leak-proof seal
• Used to seal secondary openings on washer reservoirs for models without headlight washer systems
• Direct replacement for crumbled, missing, or damaged reservoir plugs

This rubber expansion plug is frequently required when installing later-style washer fluid reservoirs on vehicles that were not originally equipped with headlight washers. The plug seals the opening where the headlight washer pump would normally mount, preventing fluid leaks and contamination.
