Description
Overview:
This genuine Stihl insulator (OEM 1130 405 8000) is a heat‐resistant, black polymer block that sits between the engine and carburettor to thermally and mechanically isolate key components. It helps reduce vibration transmission, limits heat soak into the carburettor, and maintains a reliable air seal on popular compact chainsaws such as the Stihl 017 and MS 170. By controlling heat transfer and movement, the insulator supports stable idling, clean acceleration, and consistent tuning in both domestic and professional use. Built for the demanding conditions of everyday cutting, it provides an exact OEM fit to restore correct alignment and sealing of the intake path, protecting the engine from unmetered air leaks and helping extend the service life of surrounding parts.
Key Features:
- Genuine Stihl part for assured fit and compatibility (OEM 1130 405 8000)
- Heat-resistant polymer construction helps prevent carburettor heat soak
- Reduces vibration transfer to support stable idle and smooth throttle response
- Maintains an air-tight seal at the intake to protect against lean running
- Durable, corrosion-free material suitable for harsh, dusty environments
- Designed for quick, straightforward replacement with standard workshop tools
- Supports long-term engine health by reducing wear on adjoining components
- Direct replacement for worn, cracked, or warped intake insulators
Typical Applications:
Routine maintenance and repair of Stihl chainsaws to cure air leaks, erratic idle, hard starting, or tuning drift caused by a deteriorated intake insulator. Suitable for regular servicing in landscaping, forestry, carpentry, and general property maintenance, helping keep light-duty to mid-duty saws running reliably across seasonal temperature changes and daily cutting tasks.
Also known as:
Carburettor insulator, intake insulator, insulating flange, carb spacer, manifold insulator, intake block, isolator block, carb mount insulator, thermal insulator block.
