Description
Overview:
This genuine Stihl gasket (OEM No. 4180 129 0907) is a small but critical sealing component used in Stihl handheld petrol machines such as brushcutters and pole pruners. Made from durable gasket-grade material designed to resist heat, fuel and oil, it sits between mating engine components to maintain an airtight, leak-free joint. A sound seal helps preserve vacuum and compression, supports stable idling, and protects against unmetered air or fluid leaks that can reduce performance. Purpose-built for Stihl 4-MIX platforms including the FS 91 and FS 111, it offers an accurate fit that supports reliable operation in professional landscaping and domestic garden work. Being a genuine Stihl part ensures compatibility and consistent performance within the intended engine assemblies.
Key Features:
- Genuine Stihl part for assured compatibility and performance
- OEM No. 4180 129 0907 for easy identification
- Precise fit for listed Stihl 4-MIX machines to maintain correct tolerances
- Helps prevent air and fuel leaks for smoother running and dependable starting

- Stable dimensions and consistent thickness for reliable sealing between flat faces
- Ideal for preventative maintenance or during related repairs (e.g. intake or engine service)
- Simple to install during routine servicing with basic hand tools
- Reduces the risk of avoidable wear, poor idle and unplanned downtime
Typical Applications:
Used during service or repair of Stihl handheld engines where a sealing joint must be renewed, such as intake-side work, engine strip-downs, or when diagnosing air leaks. Suitable for restoring correct sealing after component replacement, resolving poor idle or hard starting, and maintaining reliable day-to-day operation in landscaping, grounds maintenance and domestic gardening tasks.
