Description
Overview:
The Exhaust Gasket 1123 149 0500 is a genuine Stihl part designed to seal the joint between the cylinder and muffler on Stihl petrol chainsaws. Made from a heat‐resistant gasket material, it provides a tight, durable seal that helps maintain correct back pressure, minimise exhaust leaks, and protect nearby components from hot gases. This gasket is a direct OEM fit for Stihl models such as the 021 and 023, ensuring proper alignment with the exhaust port and bolt pattern. Using the correct gasket helps preserve engine performance, reduce noise leakage, and support safe, efficient running after muffler removal or service. Supplied as a single gasket, it is suitable for routine maintenance or muffler/cylinder work where the old seal is damaged or compressed.
Key Features:
- Genuine Stihl OEM gasket for reliable fit and function (MPN: 1123 149 0500)
- Heat‐resistant sealing material helps prevent exhaust leaks and blow‐by
- Supports correct exhaust back pressure for stable performance and idle
