Description
Overview:
This Cylinder Gasket is a genuine Stihl part designed for the HS82 and HS87 hedge trimmers. It sits between the cylinder and crankcase to create a reliable airtight seal, helping to maintain correct compression and prevent air, fuel, or exhaust leaks. Made from OEM-grade gasket material suited to high-temperature, two-stroke applications, it supports smooth running and protects internal engine components from premature wear. A precise factory profile ensures correct alignment of ports and fastener holes, making it suitable for routine servicing or a cylinder rebuild. Using the correct gasket helps restore performance, reduce erratic idling, and aid starting, especially after disassembly or when the old gasket has deteriorated. This part corresponds to Stihl MPN 4237 029 2301 and matches original specifications for fit and thickness.
