Description
Overview:
This Muffler/Exhaust Gasket is a genuine Stihl part for HS 75 and HS 80 hedge trimmers (also suitable for HS 85). It sits between the exhaust port and the muffler/silencer to form a tight, heat‐resistant seal. Made from durable, high‐temperature gasket material, it resists exhaust heat and engine vibration to prevent gas leaks and maintain correct back pressure. A good seal supports reliable starting, smooth idling and consistent performance, while helping to keep exhaust noise and fumes directed away from the user. Designed to the original specification, OEM Part No. 4226 149 0605 fits correctly without trimming. Ideal when refitting the silencer or after any exhaust service, this flat gasket provides a clean, dependable interface that protects mating surfaces from blow‐by and erosion.
Key Features:
- Genuine Stihl component for assured compatibility and quality
- OEM reference 4226 149 0605 for accurate identification and fit
- Heat‐resistant gasket material handles high exhaust temperatures and repeated heat cycles
- Maintains proper exhaust back pressure to support power and smooth running
- Helps prevent exhaust leaks, fumes and noise escaping at the joint
- Protects cylinder and muffler faces from hot gas erosion and carbon tracking
- Pre‐cut holes align with factory studs for straightforward installation
- Stable under vibration; resists crushing and premature blow‐out
- Ideal to replace whenever the silencer is removed or serviced
- Matches the original profile for a neat, leak‐free seal
Typical Applications:
Used during routine servicing or repairs of Stihl HS‐series hedge trimmers when removing or refitting the muffler. Replace if the old gasket is torn, brittle, sooted, or leaking. Suitable for curing symptoms such as exhaust fumes at the flange, increased noise, poor idle, or carbon marks around the joint. Recommended whenever the cylinder, muffler, spark arrester or exhaust bolts are disturbed.
