Description
Overview:
This Exhaust Gasket is a genuine Stihl part for sealing the joint between the cylinder and the muffler on a wide range of Stihl handheld machines, including hedgetrimmers such as the HS45 and HS81. Manufactured from heat‐resistant gasket material, it creates a tight seal to prevent exhaust leaks, maintain correct back pressure, and protect nearby components from hot gases. A sound exhaust seal supports smooth starting, stable idling, and full power under load. Designed to match OEM No. 4140 149 0602, it aligns accurately with the port and fixing holes for reliable, repeatable fitting. Suitable for routine servicing or repairs where the muffler has been removed, this gasket is a simple, effective way to keep your Stihl equipment running cleanly and efficiently. Genuine Stihl part for assured compatibility.
Key Features:
- Genuine Stihl part for exact fit and reliability (OEM 4140 149 0602)
- Heat‐resistant construction to withstand high exhaust temperatures
- Accurate bolt-hole and port alignment for quick, tidy installation
- Helps prevent exhaust leaks, fumes, and soot blow‐by towards the operator
- Supports correct exhaust back pressure for smooth running and performance
- Durable sealing surface resists crushing and vibration over time
- Ideal to replace whenever the muffler is removed during servicing
- Compatible across many Stihl hedge trimmers, brushcutters, blowers, and Kombi units
Typical Applications:
Used during muffler or cylinder servicing, spark arrestor cleaning, or when addressing exhaust leaks, poor idle, excess noise, or visible soot at the exhaust joint. Replace the gasket whenever the muffler is removed to ensure a reliable seal and to protect engine performance on Stihl handheld equipment used in gardening, landscaping, and grounds maintenance.
