<p><strong>SMART-O®</strong> is the most advanced oil drain plug in the market, designed to offer a complete solution for the changing of oil dain plugs, prevents sudden and catastrophic oil loss, oil leaks, oil pan damage and ultimately engine damage.</p> <p><strong>SMART-O®</strong> oil drain plug is designed to protect engines and the oil pan. In a different way than magnetic oil drain plugs, SMART-O® reduces wear on the oil pan thread and reduces risk for catastrophic oil loss which could damage the engine.</p> <p><strong>Safe Seal Function</strong></p> <p>Intelligent material O-Ring expands up to 10% - 20% when exposed to engine oil. This seals the oil pan from inside the thread rather than just from the outside. </p> <p>SMART-O® plugs provide powerful, safe sealing beyond any other oil drain plug system in the market.</p> <p>The use of SMART-O® plug prevents oil leaks and ultimately engine damage.</p> <p><strong>Anti-Vibration</strong></p> <ul> <li>O-Ring acts as an interference to prevent natural self-closing of plug, caused by engine vibration.</li> <li>This prevents SMART-O® from falling out due to vibration over time, if not tightened properly.</li> <li>This also prevents self-loosening through vibration, oil leaks and ultimately engine damage.</li> </ul> <p>*Tested by the Oakland University Fastening & Joining Institute and Spectrum Technologies, Michigan.
