It maintains a tight seal around the valve stem, preventing contaminants from entering the combustion chamber and oil from escaping. Proper sealing reduces oil consumption, emissions, and engine wear, contributing to overall engine health. Made from high-quality materials, it resists heat and chemical degradation, ensuring long-lasting performance. Correct installation of this seal is essential for maintaining engine efficiency and preventing costly repairs.
