Description
Overview:
This Gasket Cylinder is a genuine Husqvarna sealing gasket for professional two-stroke chainsaws, built to maintain engine compression and stop air, fuel and oil leaks at the cylinder base. Made from durable composite fibre gasket material, it sits between the cylinder and crankcase to keep the top end airtight under high temperature and vibration. It is engineered for a precise OEM fit on Husqvarna 572 XP and 565 machines, with accurately cut holes for ports and fasteners to make positioning straightforward. Using a correct, model-specific base gasket helps the engine start reliably, hold tune, and deliver consistent power, while reducing the risk of air leaks that can lead to poor running or damage. Genuine Part status provides reassurance on compatibility and long-term performance.
Key Features:
- Genuine Husqvarna part for correct fit and compatibility
- Robust composite fibre construction for temperature and vibration resistance
- Precision cut-outs align with ports and bolt holes for easy placement
- Maintains compression and prevents leaks to protect engine integrity
- Helps stable idling, clean acceleration and consistent power delivery
- Suitable for routine top-end servicing and rebuilds without modification
- Designed for professional two-stroke chainsaw use in demanding conditions
Typical Applications:
Used during top-end rebuilds, piston or cylinder replacement, and leak cures on Husqvarna professional chainsaws. Ideal when reassembling after de-coking, diagnosing hard starting, poor idle, or inconsistent tuning caused by air leaks. Also suited to preventive maintenance to restore an airtight factory seal and prolong engine life in daily forestry, arborist and heavy-duty cutting work.
