Engine Crankshaft Seal 710841

The National 710841 Premium Engine Crankshaft Seal is engineered to rigorous original equipment (OE) standards to maintain an airtight fluid boundary along your engine’s rotating crankshaft. This heavy-duty dynamic lip seal isolates the high-pressure motor oil environment inside the crankcase, effectively resolving common automotive failures such as severe engine oil leaks, premature drive belt slipping due to oil saturation, and timing cover oil accumulation. Its precision-molded architecture handles high-RPM shaft rotation smoothly while preserving a tight fluid barrier across severe thermal cycles.
