Description
Overview:
This Muffler/Exhaust Gasket is a genuine Stihl part designed to seal the joint between the cylinder exhaust port and the silencer on heavy‐duty brushcutters and clearing saws. Built from heat‐resistant gasket material suitable for high exhaust temperatures and vibration, it prevents blow‐by gases and oil residue from escaping, helping the machine run smoothly and efficiently. A correct seal supports proper back pressure, maintains power, and reduces noise. Engineered for a precise fit on Stihl professional machines, including FS 450 and SP 450, it is a direct replacement that restores the integrity of the exhaust system after service work. Genuine Stihl quality ensures reliable compatibility and performance under demanding site and vegetation‐clearing conditions.
Key Features:
- Genuine Stihl part for assured fit and reliability
- Heat‐resistant gasket material designed for exhaust temperatures and vibration
- Creates a gas‐tight seal to prevent leaks, loss of power, and carbon staining
- Helps maintain correct exhaust back pressure for consistent engine performance
- Supports noise control by preventing exhaust leakage at the flange
