4226 149 0600 STIHL Muffler Gasket Genuine OEM Part
The STIHL Muffler Gasket (4226 149 0600) is a genuine OEM replacement gasket designed for use on select STIHL hedge trimmers. This gasket forms a critical seal between the muffler and the engine cylinder, preventing exhaust leaks and ensuring proper exhaust flow and engine performance.
A properly sealed muffler gasket helps maintain correct back pressure, reduces exhaust noise, and prevents hot exhaust gases from escaping toward sensitive engine components. A worn, damaged, or leaking gasket can cause loss of power, increased noise, overheating, or exhaust residue buildup.
Manufactured to STIHL factory specifications, this OEM muffler gasket ensures correct fitment, reliable sealing, and long-term durability under professional operating conditions.
