Description
Overview:
This Muffler/Exhaust Gasket is a genuine Stihl part (OEM 1115 149 0600) designed to seal the joint between the cylinder exhaust port and the muffler on two-stroke machines. Made from a heat-resistant, pressure-stable composite, it provides a gas-tight seal that withstands sustained high temperatures and vibration. By preventing exhaust leaks, it helps maintain engine performance, correct back pressure, and safe operation. It is built to Stihl's factory dimensions for a direct fit on the specified machines, avoiding guesswork or modification. Suitable for backpack leaf blowers such as the BR320 and BR320L, and a range of other compatible Stihl equipment listed below. As a wear item, it is commonly replaced during routine servicing or whenever the muffler is removed.
Key Features:
- Genuine Stihl part for assured compatibility and quality
- OEM reference 1115 149 0600 for easy identification
- Heat- and pressure-resistant construction helps prevent blow-by and leaks
- Maintains correct exhaust back pressure for stable idle and power
- Durable sealing material resists crushing, burning, and vibration
- Precise cut profile for a clean, accurate fit to mating surfaces
- Straightforward replacement with standard hand tools
- Suitable for routine maintenance and post-repair reassembly
Typical Applications:
Used when refitting the muffler after servicing, decarbonising, or repairs; to cure exhaust leaks causing fumes, noise, loss of power, or soot marks; and as preventative maintenance on high-hour machines. Recommended to replace the gasket whenever the muffler is removed on applicable Stihl backpack blowers and related machines to ensure a reliable gas-tight seal.
