Description
Overview:
This Muffler/Exhaust Gasket is a genuine Stihl spare part designed to seal the joint between the cylinder and muffler on Stihl chainsaws.

It is purpose‐made for Stihl saws and fits accurately on the mounting face to protect both the cylinder and muffler surfaces. Suitable for professional users and DIY maintenance, it is ideal when refitting the exhaust after servicing or whenever a leak is suspected. Genuine Stihl part, OEM reference 1120 149 0601.
