• Function

1.Sealing Engine Oil: Its primary role is to retain engine oil within the engine. It forms a tight seal around the crankshaft to prevent oil from leaking out of the crankcase. This is crucial for maintaining the proper oil level and lubriion within the engine, which in turn ensures smooth operation and reduces wear on engine components.

2.Preventing Contamination: The seal also acts as a barrier to keep external contaminants, such as dust, dirt, and debris, from entering the engine oil system. Contamination can cause damage to engine parts and reduce the effectiveness of the oil, so preventing it is essential for the longevity and performance of the engine.
