This STIHL piston ring is a precision replacement part designed for select STIHL chainsaws. The piston ring seals the combustion chamber to maintain compression and prevent blow-by—the leakage of gases past the ring into the crankcase. A worn piston ring reduces engine performance and efficiency.
This replacement ring is engineered with a precision-fit design and optimized ring gap to ensure consistent sealing and uniform pressure distribution across the cylinder wall. The built-in oil control features limit oil blow-by, preserving smooth engine operation and reducing emissions.
