Material and durability Made from ABS plastic with good heat resistance and antiaging properties. Rigid construction that resists cracking, breaking, or deformation during normal use. Key benefits — why you need it Prevents washer fluid loss by providing a tight, accurate seal to the windshield washer tank, reducing leakage and evaporation. Keeps dust, dirt, and moisture out of the washer reservoir so the washing system runs as intended. Durable design means fewer replacements and consistent performance over time. What makes it stand out Precisely molded cover that fits the washer tank securely — not loose or wobbly. Simple, tool installation: align the card slot and press to engage for a reliable fit. Purposebuilt for windshield washing systems; avoids unnecessary features and focuses on protecting the reservoir. Function and compatibility Designed specifically for windshield washer systems and washer tanks. Acts as a protective cap to stop contaminants and moisture from entering the fluid reservoir and interfering with the system's operation. Compact, exactfit design ensures compatibility where a matching washertank cover is required (verify fit for your vehicle model before ). Installation Plugandplay: line up the card slot and press gently until it snaps into place. No tools or technical expertise needed; removal is equally straightforward. Typical applications Everyday vehicle maintenance: keeps washer fluid clean and the washing system operating reliably in daily use. After offroad or muddy driving: prevents debris and grit from contaminating the reservoir following dusty or muddy trips. Seasonal protection and storage: limits evaporation and moisture entry when the vehicle is parked for extended periods or during temperature changes. What you get A single, durable ABS plastic cover engineered to protect the windshield washer tank and help maintain the normal operation of the washing system.
