The MS660 oil seal set is a dedicated sealing part for MS660 high-power chainsaws, featuring two sizes (large/small) to match different core components (e.g., crankshaft, drive system). Its material (Fluorelastomer) offers excellent oil resistance and heat tolerance, enduring the high temperatures and heavy oil immersion of high-power operation.

Precisely machined to match the MS660’s original seal slots, the set installs without gaps. The flexible seal lip adheres tightly to shaft surfaces, locking in lubricating oil while blocking dust, wood chips, and other debris—keeping the chainsaw's internal parts clean and protected during intense logging tasks.
