Description
Overview:
This genuine Stihl gasket (MPN 4134 129 0900) is a precision-cut sealing component used to create a tight, reliable joint within engine assemblies. Made from a fuel- and heat‐resistant composite material, it helps prevent air, fuel, and oil leaks that can affect starting, performance, and emissions. It is designed for Stihl brushcutters, clearing saws, and related tools, including FR350 and FR450, and is widely used across compatible models for dependable sealing between mating surfaces. A correct, undamaged gasket is vital whenever components such as intake, carburettor, or housing interfaces are assembled, ensuring stable idle, full power, and long service life. As a genuine Stihl part, it delivers the right fit and durability for professional and domestic users.
Key Features:
- Genuine Stihl part for assured compatibility and fit
- Fuel- and heat‐resistant composite material for long service life
- Helps maintain correct compression and stable engine performance
- Reduces the risk of air, fuel, and oil leaks at mating surfaces
- Precision-cut profile for straightforward alignment during fitting
- Consistent thickness for even clamping and proper torque retention
- Suitable for routine maintenance and engine rebuilds
- Supports reliable cold starting and smooth running under load
Typical Applications:
Used when assembling or reassembling engine components on compatible Stihl machines to restore a positive seal. Typical tasks include intake/carburettor refits, top‐end servicing, and general engine maintenance on brushcutters and similar tools. Replace whenever a joint is disturbed, or when symptoms such as erratic idle, loss of power, or visible seepage occur, to maintain performance and protect internal parts.
