Description
Overview:
This Genuine Stihl gasket (OEM Part No. 4238 129 0901) is a precision-cut sealing component for Stihl cut-off saws such as the TS 410 and TS 420. Made from heat- and fuel-resistant composite gasket material, it creates a reliable seal between mating surfaces in the engine or intake assemblies. A correct seal helps maintain vacuum and compression, prevents air and fluid leaks, and supports clean carburation for consistent performance. Built to handle the vibration and temperature cycles typical of petrol-powered disc cutters, it helps reduce the risk of hard starting, rough running, or loss of power caused by air leaks. Ideal for routine servicing or repairs where a worn, flattened, or damaged gasket needs replacing. This is a Genuine Part for assured compatibility and long service life.
