Description
4228 649 0301 STIHL Gasket – Genuine OEM Part
The STIHL Gasket (4228 649 0301) is a genuine OEM replacement sealing gasket designed for use on select STIHL hedge trimmers. This gasket is used in the gear head and handlebar with hand guard assembly, providing a critical seal that helps protect internal components and maintain proper lubrication and performance.
A properly installed gasket prevents grease leakage, contamination, and loss of sealing integrity within the gear head area. A worn or damaged gasket can lead to lubricant loss, increased wear, overheating, or reduced cutting performance.
Manufactured to STIHL factory specifications, this OEM gasket ensures correct thickness, precise fitment, and long-lasting durability under professional trimming conditions.
