Description
Overview:
This gasket is a genuine Stihl OEM sealing component for the MS 270 and MS 270 C chainsaws. It is designed to sit between engine mating surfaces to maintain an airtight, fuel-tight, and oil-tight joint, helping to protect performance and reliability. Made from durable, heat‐resistant compressed fibre material, it withstands engine temperatures, vibration, and exposure to petroleum-based fluids. The profile is precision cut to match the factory geometry for an accurate fit and consistent sealing. It is suitable for routine servicing or full rebuilds where the original gasket has been disturbed or has aged. Supplied under Stihl part number 1133 029 0500, it provides a like‐for‐like replacement for specified models to help keep your saw running efficiently and starting reliably.
