Description
4147 129 0901 STIHL Gasket Genuine OEM Part
The STIHL Gasket (4147 129 0901) is a genuine OEM sealing gasket designed for use in the air filter / spacer flange assembly on select STIHL brushcutters and clearing saws.
This gasket helps create a proper seal in the spacer flange / air filter area to prevent air leaks and ensure that all intake air passes through the air filter before entering the engine. Replacing a worn, torn, hardened, or flattened gasket helps maintain correct airflow, engine performance, and long-term reliability.
Manufactured to STIHL factory specifications, this OEM gasket provides correct fitment, proper sealing, and long-lasting durability.
