Description
Overview:
This Genuine Stihl gasket (part number 1128 129 0906) is a precision-cut engine sealing component for Stihl petrol chainsaws, including the 044 and MS270.

A sound gasket helps maintain correct compression and crankcase vacuum, reduces the risk of air leaks, and supports clean carburation and reliable running. It is suitable for professional and DIY maintenance, from routine strip-downs to full rebuilds, and is designed to match OEM dimensions for a dependable fit on the compatible Stihl models listed below. As a genuine part, it is built to meet Stihl's specifications for durability and sealing performance.
