About This

【COMPLETE 16-PC KIT】 Includes 8 red and 8 green premium fiber washers. The color-coding (Red for Positive+, Green for Negative-) ensures quick and correct installation, preventing dangerous reverse polarity connections.
【STOP CORROSION & EXTEND BATTERY LIFE】 Our washers are infused with a special sealant that neutralizes battery acid fumes. This creates a protective barrier on terminals, preventing corrosive buildup that leads to power loss, hard starts, and expensive battery replacements.
【FLEXIBLE UNIVERSAL FIT】 Features a unique dual-ring design. The outer diameter is 1.73 inches. For standard terminals (approx. 0.79 in), use the inner ring. Simply punch out the inner ring for a 1.18-inch opening to fit larger post terminals, making them ideal for cars, trucks, RVs, and lawn equipment.
【HEAVY-DUTY & CHEMICAL RESISTANT】 Made from durable, compressed fiber material resistant to battery acid, oil, and extreme engine bay temperatures. They provide a long-lasting, protective seal that cheap felt washers can't match.
【EASY INSTALLATION & COST SAVING】 Installation takes seconds! Just place a red washer on the positive (+) terminal and a green one on the negative (-) terminal before connecting the cables. A small investment protects your battery, cables, and terminals, saving you hundreds on premature repairs.
