Genuine STIHL MS311 MS362 MS391 Exhaust Muffler Gasket – 1140 149 0600

Genuine STIHL exhaust / muffler gasket designed to provide a secure gas-tight seal between the cylinder and muffler assembly on selected STIHL chainsaws. This OEM gasket helps prevent exhaust leaks, maintains correct back pressure and supports optimal engine performance and throttle response.

Manufactured from heat-resistant gasket material, the 1140 149 0600 gasket is ideal for routine servicing, muffler replacement, cylinder repairs and top-end rebuilds. Replacing the gasket whenever the muffler is removed helps avoid leaks, excessive exhaust noise and power loss.
