The re-lubricated seal of the O-ring is better than the gaskets of other brands. Efficient filter paper protects the engine from contamination, making installation convenient and accurate, preventing oil leakage under excessive torque. The silicon antibacterial valve prevents excessive oil from flow-ing out, which could lead to engine shutdown. High dust capacity, high-quality filter paper has greater dust capacity, extending the service life of the filter element; excellent structural stability, resistant to high temperatures and corrosion without deformation, remaining stable throughout the usage period.
