Description
Overview:
This is a genuine Stihl gasket (part number 4149 129 0902) for small petrol-powered tools. It creates a tight, leak-free joint between mating surfaces in the engine or related housings, helping maintain correct running and overall reliability. Made from durable, fuel‐ and heat‐resistant gasket material suitable for outdoor power equipment, it is designed for repeated thermal cycles and vibration. Ideal for Stihl brushcutters and hedge trimmers, it supports proper operation by preventing unwanted air, fuel or oil leaks that can lead to poor performance. It is a direct replacement for worn or damaged gaskets on models such as the FS 94 and FS 94 C. As a genuine Stihl component, it offers the correct profile and fit for consistent results in routine maintenance or repairs.
