Description
Overview:
This genuine Stihl OEM muffler gasket (part number 1144 149 0600) seals the joint between the cylinder exhaust port and the silencer on Stihl professional chainsaws. Made from a heat-resistant composite gasket material designed for high temperatures and vibration, it provides a gas-tight seal that helps prevent exhaust leaks, soot blow‐by, and loss of performance. A correct seal also helps maintain proper back pressure and stable idle. Purpose-made for Stihl machines, it fits precisely without trimming or modification. Ideal for routine service or repairs on hard‐working saws, it restores reliable exhaust sealing and supports safe, efficient running. Suitable for heavy-duty forestry and firewood work, it is a direct-fit replacement for models including the MS 661 and MS 661 C.
Key Features:
- Genuine Stihl OEM part for assured fit and quality (1144 149 0600)
- Heat-resistant composite construction for long service life under high exhaust temperatures
- Precise alignment to the cylinder and muffler for a consistent gas-tight seal
- Helps preserve power, throttle response, and correct exhaust back pressure
- Reduces risk of hot gas leakage that can mark plastics or nearby components
- Flat, two-hole pattern matches the original gasket for straightforward installation
- No modifications required; compatible with factory fasteners and housings
- Reliable choice for professional users and demanding domestic applications
- Suitable to replace a worn, damaged, or compressed gasket during exhaust or top-end service
Typical Applications:
Used when refitting the silencer after decarbonising, during top-end overhauls, or to cure exhaust leaks indicated by noise changes, fumes, or soot marks around the muffler joint. Common in forestry, arborist work, firewood processing, site clearance, and general maintenance of Stihl professional chainsaws.
