Description
Overview:
This Cylinder Gasket is a genuine Stihl part designed for small 2‐stroke engines used in brushcutters and hedge trimmers, including the Stihl FS 38 and FS 45. Fitted between the cylinder and crankcase, it creates a tight, heat‐resistant seal to maintain compression and prevent air, fuel, and oil leaks. Made from durable, heat‐resistant composite gasket material, it withstands vibration, temperature changes, and exposure to fuel mix. Using the correct OEM gasket helps the engine start reliably, idle smoothly, and deliver consistent power. It is suitable for routine maintenance or top‐end repairs where the cylinder has been removed. Part number 4140 029 2302 ensures the correct profile and port cut‐outs for the intended Stihl machines.
