The SR420 oil seal is a dedicated sealing part for SR420 chainsaws, with two sizes (large/small) to match key components (e.g., crankshaft, drive shaft). Its oil-resistant rubber body withstands long-term engine oil immersion and the vibration of logging tasks, avoiding swelling or cracking.

Precisely machined to the SR420's original seal slots, the set installs without gaps. The flexible seal lip adheres closely to shaft surfaces, locking lubricating oil inside while blocking wood debris and dust—keeping the chainsaw's internal parts clean and reducing wear during heavy use.
