Description
Overview:
The Muffler/Exhaust Gasket is a genuine Stihl sealing component for handheld two-stroke machines. It fits between the cylinder exhaust port and the muffler to create a secure, gas‐tight joint. Made from a heat‐resistant composite material, it maintains the seal under high temperatures and vibration to prevent leaks, noise and loss of power. This direct replacement matches OEM specification MPN 4137 149 0600 and suits a wide range of Stihl brushcutters, trimmers and attachments, including SP81 and FR85T. A good exhaust seal supports correct back pressure, cleaner running and safer operation by keeping fumes directed away from the user. It is a simple service item that can restore performance when refitting the silencer after maintenance or when a leak is found.
