The Cylinder Gasket 0.5 mm for Stihl chainsaws is a genuine Stihl OEM sealing gasket for the cylinder base, designed to sit between the crankcase and the cylinder to maintain a reliable, air‐tight seal. Made from a durable fibre‐reinforced composite, it resists heat, fuel and oil, helping to prevent air leaks and preserve correct engine compression for consistent performance. Its 0.5 mm thickness (approx. 0.02 in) matches factory specification, supporting a precise fit without added sealants when surfaces are clean and true. Cut-outs align with studs and ports for straightforward assembly. Suitable for petrol two‐stroke chainsaws such as the Stihl MS 240 and MS 260, it is an essential service part for routine maintenance and top‐end rebuilds. Genuine Part: Stihl 1118 029 2306.
