The 96400032257 is a genuine STIHL oil seal, sized 20 × 42 × 5 mm.
It is also listed as DIN 3760‑BS 20×42×5 in spare parts catalogs.
This seal is used in models such as STIHL TS710.0i, TS800, TS910.0i, TS700, etc.
The oil seal’s role is to prevent oil leakage and to keep contaminants like dirt and water out of internal mechanisms (e.g. crankcase, crankshaft areas)
It’s typically used in the cutting / drive / crank areas of power tools where shafts rotate, especially in models that have oil lubrication systems
Because of its dimensions (20 mm inner, 42 mm outer, 5 mm width), this is a medium‑sized seal — make sure to match those dimensions when searching for equivalents
We strive for every transaction to be five stars!
