Description
Overview:
This Genuine Stihl gasket (OEM 4180 129 0905) is a precision-cut sealing component used in two-stroke Stihl engines to stop air, fuel, and oil leaks and to maintain proper compression. Made from a durable, heat-, oil-, and fuel-resistant compressed fibre composite, it provides a secure seal between mating engine parts for consistent performance and easier tuning. Suitable for a wide range of Stihl handheld machines used in landscaping, forestry, and construction, including brushcutters, earth augers, pole pruners, and Kombi engines. Designed for reliable fitment on popular models such as the FR130T and HT130, it helps protect internal components, stabilise idle and acceleration, and extend service life when replaced during routine maintenance or after a tear-down.
Key Features:
- Genuine Stihl part for assured compatibility and build quality
- OEM reference 4180 129 0905 for accurate identification and fit
