Powder-coated tank vent cap replacement is manufactured to fit onto a tank vent cap base. Acts as a physical barrier to ambient environment, reducing evaporation of fuel due to temperature changes. Prevents pressure from building up in tank and releases vacuum, allowing for consistent pump performance despite environmental conditions. Prevents contaminates like dirt, rust, and water from entering your fuel supply, ultimately maintaining quality and protecting your equipment. Threaded tank base is finished with a powder coating, providing long-term corrosion resistance and lifetime performance.
