Description
Overview:
This Genuine Stihl gasket (MPN 1121 029 0500) is a precision-cut, fuel- and heat‐resistant composite designed to restore a tight seal within the engine of petrol chainsaws. It prevents air, fuel, and oil leaks across mating surfaces such as key engine joints, helping maintain correct crankcase vacuum and compression.
