The Oil Filter Buffer Seal is situated between the oil filter housing and the engine block, forming a tight seal to prevent oil leakage. As oil is pumped through the engine, it passes through the filter housing, where the buffer seal ensures that the oil is directed through the filter media for efficient filtration. By preventing leaks, this seal helps to preserve the engine's oil supply and ensures that only filtered oil is circulated, thus protecting engine components from damage and maintaining optimal performance.Attributes:• Resists swelling and shrinking.• Resistant to oil degradation.• Withstands high temperatures. • Resilient against pressure fluctuations.• Suitable for 101.55mm diameter rod.•Applications: The Oil Filter Buffer Seal is used to create a secure and leak-proof seal between the oil filter and the engine housing, preventing oil leaks and ensuring proper filtration of engine oil.
