The MS250 oil seal is a dedicated sealing part for MS250 chainsaws. Its high-grade oil-resistant rubber body withstands long-term immersion in engine oil (no swelling or cracking), while the precision-machined outer/inner diameters fit exactly into the MS250's seal slots.

Designed for key positions (e.g., crankshaft, drive components) of the MS250, it installs tightly without gaps. The flexible rubber lip adheres closely to the shaft surface, preventing oil from leaking out and dust/wood debris from getting into internal parts, keeping the chainsaw's lubrication system efficient.
