Description
Overview:
The Exhaust Gasket for Stihl TS400 is a genuine Stihl OEM sealing plate that sits between the cylinder exhaust port and the muffler. Made from a heat‐resistant composite designed for high temperatures and vibration, it prevents hot gas leaks and helps maintain correct backpressure for stable performance. This gasket keeps exhaust joints gas‐tight, supports efficient scavenging in two‐stroke engines, and protects nearby components from heat and soot. It is precision‐cut to the correct profile for a reliable fit on the TS400 cut‐off saw and many Stihl chainsaws, including the MS360. Supplied under Manufacturer Part Number 1125 149 0601, it is a straightforward replacement during routine maintenance or when refitting the muffler after engine or exhaust work.
Key Features:
- Genuine Stihl OEM part for assured compatibility and reliability (MPN 1125 149 0601)
- Heat‐resistant composite suitable for sustained high exhaust temperatures
- Precision profile and bolt holes for accurate alignment and secure sealing
- Helps prevent exhaust blow‐by, power loss, and carbon staining around the joint
- Supports correct exhaust backpressure for smooth running and throttle response
- Robust under vibration and frequent heat cycles typical of site and forestry use
- Ideal to replace whenever the muffler is removed or an exhaust leak is suspected
- Clean, flat sealing faces promote quick fitting with consistent results
- Suitable for the Stihl TS400 and a wide range of listed Stihl chainsaws
- Replaces worn, crushed, or heat‐damaged gaskets to restore efficiency
Typical Applications:
Used when servicing or rebuilding engines, replacing mufflers, decarbonising exhaust systems, or curing exhaust leaks on Stihl cut‐off saws and chainsaws. Common on site work, landscaping, arborist jobs, and workshop maintenance to ensure safe, efficient running, reduce noise leakage, and protect the cylinder and mounting faces from erosion caused by escaping hot gases.
