Description
Overview:
The Stihl insulator (part number 1130 405 8004) is a genuine thermal barrier used in compact petrol chainsaws to limit heat transfer between hot engine parts and the intake assembly. Made from a heat-resistant polymer composite, it helps stabilise running by protecting the carburettor and nearby components from excess heat. This improves reliability, especially during prolonged cutting. It is designed for small Stihl saws such as the MS 170 and MS 180, providing an exact fit in the original mounting position. By maintaining consistent temperatures around the intake, the insulator helps reduce vapour lock and fuel perishing, supports clean idling, and extends service life. It is a direct replacement for worn, cracked, or heat-damaged original insulation blocks. Genuine Stihl part for assured compatibility.
Key Features:
- Genuine Stihl component for precise fit and compatibility
- Heat-resistant construction helps reduce heat soak into the carburettor
- Supports consistent starting, idling, and throttle response
- Helps prevent vapour lock and premature fuel line or gasket degradation
- Durable polymer composite designed for regular, demanding use
- Straightforward to fit with basic tools as a like-for-like replacement
- Stable geometry and sealing surfaces for reliable intake alignment
- Suitable for routine servicing or preventative maintenance
Typical Applications:
Used during routine servicing or repairs of Stihl homeowner and light professional chainsaws to restore thermal protection around the intake system. Replace when the original insulator shows cracks, warping, or heat damage, or when diagnosing hot-start issues, erratic idle, or fuel vaporisation problems during prolonged cutting or warm weather use.
