Stihl 4137 149 0600 Exhaust Gasket

This muffler and exhaust gasket is a genuine Stihl component designed for handheld two-stroke machines. It installs between the cylinder exhaust port and the muffler to form a secure, gas-tight seal. Constructed from heat-resistant composite material, it withstands high temperatures and vibration to prevent exhaust leaks, reduce noise, and maintain engine power. This direct-fit replacement meets OEM specification MPN 4137 149 0600 and is compatible with a variety of Stihl brushcutters, trimmers, and attachments, including models SP81 and FR85T. Maintaining a proper exhaust seal ensures correct back pressure, cleaner engine operation, and safer use by directing fumes away from the operator.
