Description
Overview:
This genuine Husqvarna Gasket Kit is a model-specific sealing pack for selected chainsaws, including the 235 and 550 XP. Made from durable fibre and composite gasket materials chosen for fuel, oil, and heat resistance, it restores reliable seals between key engine and exhaust interfaces. Correct sealing is essential for maintaining compression, preventing air and fluid leaks, and keeping performance stable under load. The kit is designed to match OEM profiles for the stated models, helping to ensure an accurate fit without guesswork. Ideal for professional workshops and DIY users, it supports routine maintenance and repairs where gaskets have aged, been disturbed during service, or show signs of leakage.
