Windshield washer / wiper fluid reservoir cap designed to protect the reservoir and internal components from debris, rain, and weather damage. Key benefits Prevents stains and debris from entering the water tank, reducing contamination and potential damage to the washer reservoir and pump. Keeps internal components dry and protected from rain and humidity, improving reliability in wet or humid climates. Provides a tight, leakresistant seal that withstands harsh weather and reduces the chance of cracks or breakage over time. Features Material: made from automotivegrade plastic for stable, longlasting performance; lightweight and easy to carry. Seal: precisionengineered cap with gasket interface — ensures a secure fit and reliable waterproofing when properly seated. Durability: resists wear from regular use and exposure to the elements; designed for car installation and routine replacement or maintenance. Compatibility and performance Intended for use on automotive windshield washer / wiper fluid reservoirs and compatible with standard reservoir openings found in most vehicles. Performancefocused design reduces contamination, maintains internal component function, and extends the service life of the washer system. Practical use scenarios Routine replacement: swap a worn or missing cap to stop dirt and leaves from entering the reservoir after maintenance or fluid up. Rainy or humid climates: protect pump, hoses, and nozzles from moisturerelated corrosion and malfunction by keeping the reservoir sealed. Dusty or offroad conditions: prevent sand and debris from entering the system to avoid clogged nozzles and premature pump wear. Installation and maintenance tips Press the cap firmly into place and verify the gasket is seated correctly — carefully check whether the cover is sealed with a gasket to ensure full waterproofing. Inspect the cap and gasket periodically for cracks or deformation and if the seal is compromised. What it solves Stops contamination and water ingress that can lead to clogged nozzles, reduced washer performance, or damage to reservoir components. Provides a simple, durable solution to maintain washer system reliability in adverse conditions. Materials and handling Automotive quality plastic: stable, durable, and suitable for vehicle installation. Lightweight and portable for easy handling during service or replacement.
