Description
Overview:
The Gasket.Insu is a Genuine Husqvarna sealing and insulation gasket for petrol brushcutters and trimmers. Made from durable, heat- and fuel-resistant gasket material, it sits between mating components to prevent air, fuel, or exhaust leaks while helping to limit heat transfer to adjacent parts. This supports stable tuning and protects nearby plastic or composite insulators under daily use. Supplied as an exact-fit replacement for OEM No. 505 30 49-01 (also 505304901), it matches the original profile and bolt pattern for quick installation. Suitable for popular machines such as the 143RII and 236R used in landscaping and light construction. A sound gasket helps with reliable starting, clean throttle response, and consistent idle, keeping your Husqvarna equipment running efficiently and safely.
Key Features:
- Genuine Husqvarna part for assured compatibility and build quality
- Provides tight sealing to stop intake or exhaust-side leaks
- Thermal insulation helps reduce heat soak into adjacent parts
- Resistant to petrol, oil, and vibration for dependable service life
- Cut to OEM profile with precise port and bolt-hole alignment
- Helps maintain correct mixture, power delivery, and idle stability
- Straightforward to fit during routine servicing or repairs
- Suitable for tough outdoor conditions and frequent use
- Direct replacement for OEM 505 30 49-01 / 505304901
Typical Applications:
Used when refitting a carburettor or insulator block, during intake leak diagnosis, or as part of an engine refresh on Husqvarna brushcutters and trimmers. Replace whenever the joint is disturbed or the old gasket shows damage, crushing, or fuel staining. Common in professional grounds care, hire fleets, estates, and DIY maintenance to restore reliable starting, smooth running, and consistent performance.
