• Keeps dirt and debris off the mounting nut
• Helps prevent corrosion and seized wiper arms
• Simple push-fit replacement cap

This wiper arm mounting nut dust cap is designed to protect the mounting nut from dirt, grime, and moisture. By covering the nut, it helps maintain a clean interface between the wiper arm and spindle, supporting reliable wiper operation.

If moisture is allowed to enter the wiper arm mount, corrosion can occur and the arm may seize onto the wiper spindle, making removal extremely difficult. Fitting a dust cap is a simple preventative step that helps avoid damage and frustration during maintenance or repairs.
