Description
Overview:
This genuine Stihl OEM gasket (part number 1128 129 1100) is a precision-cut sealing component for professional Stihl chainsaws such as the MS640 and MS460. Made from heat- and fuel-resistant gasket material, it maintains a tight seal between engine mating surfaces to prevent air, fuel and oil leaks. A correct seal helps preserve compression, stable idle and overall performance, while reducing the risk of engine damage caused by unmetered air. Built for the demanding conditions typical of forestry, arborist and site work, this gasket supports reliable operation and long service life. It is suitable for routine maintenance or full engine rebuilds where the original gasket has deteriorated or been disturbed during service.
Key Features:
- Genuine Stihl OEM part for assured compatibility and quality
- Precise fit to restore correct engine sealing and performance
- Resistant to petrol, oil and heat for dependable service life
- Helps prevent air leaks that can cause poor starting or erratic running
- Supports correct compression and efficient combustion
- Clean, accurate holes for fasteners and ports to aid straightforward fitting
- Suitable for professional workshops and DIY maintenance alike
- Ideal during top-end refreshes, rebuilds, or when refitting mating components
Typical Applications:
Used when rebuilding or servicing Stihl chainsaw engines, especially after dismantling components that rely on a flat gasket seal. Common during cylinder or crankcase work, when addressing vacuum/pressure test failures, or when resolving symptoms such as lean running, hard starting, or oil seepage. Suitable for demanding forestry, arborist, landscaping and site maintenance environments where consistent performance is required.
