Oil seals are also dirt, lip, shaft, and grease seals. They’re simple devices installed in rotary shaft equipment to minimize the risk of lubricant leakage and prevent other foreign substances such as water, dirt, and dust from entering.
In addition to preventing oil leakage, the piston oil seal also helps to reduce friction between the piston and the cylinder wall. This is important for maximizing engine efficiency and prolonging the life of the engine components. By reducing friction, the seal helps to improve fuel economy and reduce wear and tear on the engine.
