Function and Role in the Washer System

The front windshield washer nozzle is responsible for evenly distributing fluid across the glass surface, enabling the wiper blades to effectively remove water, mud, and road debris. A properly selected nozzle:

• ensures a stable, directed fluid stream,
• limits fluid consumption through appropriate atomization,
• maintains high visibility in rain, snow, and when driving on dirty roads.

In conjunction with other elements from the Mercedes Washer Tanks, Pumps, and Nozzles group, it forms a cohesive system responsible for front windshield cleanliness.

Compatibility and OEM Selection

The offered nozzle is an original part, assigned to a specific manufacturer's reference number, which simplifies selection by OEM number and vehicle data. This ensures the user that the mounting geometry, connection diameters, and spray angle are consistent with the factory specifications for the R172 series.

When selecting, it is recommended to verify compatibility with the part number and the vehicle's service documentation to avoid installation issues and improper fluid stream operation.

Condition, Advantages of a Used Part, and Installation

The component is offered as a used part, which helps reduce repair costs while maintaining original manufacturer specifications. In practice, this means:

• factory fit for installation on the hood or cowl,
• maintenance of the correct spray profile without modification,
• direct replacement of a worn or damaged nozzle.

Installation typically involves removing the old part, connecting the fluid hose, and seating the nozzle in its factory socket, which reduces service time.

Benefits of Using an Original Mercedes Nozzle

Using an original washer nozzle in the Mercedes R172 allows for maintaining the integrity of the entire washer system according to the manufacturer's design. Key benefits include:

• stable system operation – no accidental spraying onto the bodywork or side windows,
• better cooperation with the fluid pump and reservoir,
• reduced risk of incomplete windshield cleaning at high speeds.

For users who value maintaining the vehicle's factory parameters, this is a technically consistent solution with other system components.
