Description
Overview:
This Genuine Stihl gasket (OEM 1120 029 0502) is a precision-cut sealing component for Stihl petrol chainsaws, helping to keep the engine air- and fuel-tight for stable performance. Made from a durable, fuel- and oil-resistant fibre composite, it sits between machined engine surfaces to prevent air, fuel and oil leaks, supporting correct crankcase pressure and smooth running. It is designed for direct replacement on popular compact saws such as the Stihl 012 and 009, delivering a reliable seal that protects performance over time. Ideal for routine servicing or full rebuilds, it restores the original factory fit without modification. A correct seal helps with easy starting, consistent idling and proper power delivery, especially important on two‐stroke engines used in demanding cutting tasks.
