Description
Overview:
This Muffler/Exhaust Gasket is a genuine Stihl spare designed to seal the joint between the cylinder and muffler on compatible chainsaws. Made from a heat‐resistant gasket composite, it compresses to form a gas‐tight seal that prevents exhaust leaks, helps maintain correct back pressure, and supports smooth running and power delivery. It is intended for medium‐to‐large Stihl saws used in forestry, landscaping, and farm work, including the MS311 and MS391. As an OEM part (Stihl 1140 149 0600), it offers the precise fit and reliability needed for dependable day‐to‐day operation. Fitting a fresh gasket is recommended whenever the muffler is removed, when servicing the exhaust, or if you notice increased noise, fumes, or sooting around the exhaust outlet.
Key Features:
- Genuine Stihl OEM gasket for assured compatibility and performance
- Heat‐resistant material for long service life under high exhaust temperatures
- Accurate cut‐outs and bolt holes for a clean, secure fit
- Maintains exhaust back pressure to support power, throttle response, and idle stability
- Helps prevent exhaust leaks, fumes, and excess noise
- Supports consistent emissions control and fuel efficiency
- Ideal to replace during routine servicing or muffler removal to avoid re‐use failures
- Compact, lightweight part that installs with basic hand tools
Typical Applications:
Used during exhaust system maintenance, muffler removal/refit, carbon clean‐outs, or top‐end work on Stihl chainsaws. It restores a tight seal between the cylinder and muffler to prevent leaks, reduce noise, and protect engine performance in tree surgery, firewood cutting, estate management, and general construction site tasks.
