Key benefits Maintains tire pressure even when the valve core is damaged or dirty, reducing the risk of unexpected air loss. Chrome plated brass construction provides durability and water repellence for long lasting use. Extends the service life of the original tire valve screw by protecting it from wear and corrosion. Easy installation: simply screw onto the existing tyre shaft, with no additional dust plug required. What this product offers Material and finish: chrome plated brass for strength and corrosion resistance. Function: preserves the seal and pressure when the valve core is compromised or contaminated. Compatibility: designed to screw onto the existing tyre shaft without needing extra dust plug parts. Performance: helps maintain reliable tire pressure and protects the valve area over time. How it works Installed by threading onto the existing tyre valve shaft, creating a durable plated surface that resists water and wear. If the valve core is damaged or dirty, the device helps prevent pressure loss and supports ongoing tire performance. Installation guidance Simply screw onto the existing tyre shaft until snug. No additional dust plug is required for operation. Use scenarios Routine vehicle maintenance: use on passenger cars to help prevent minor leaks from worn or dirty valve cores during regular tire checks. Fleet or multivehicle environments: reduces maintenance downtime by extending the life of the original valve screw across several tires. Harsh or moistureprone environments: chrome plated brass construction helps resist water exposure and wear, contributing to longer valve life in challenging conditions. Notes Fits standard tyre shafts and does not require extra dust plug components to function properly. Regular inspection of tires and valves is still recommended to ensure performance.
