Description
Overview:
This exhaust/muffler gasket is a Genuine Husqvarna part designed to seal the joint between the cylinder exhaust port and the muffler on petrol chainsaws. Made from heat‐resistant gasket material and precision‐cut for a tight fit, it prevents hot gas leaks, maintains correct back pressure, and helps protect surrounding components from heat and soot. It is suitable for routine maintenance and repair work on saws such as the Husqvarna 235 and 550XP. As an OEM component, it matches the original dimensions and bolt spacing for dependable sealing and long service life. Regular replacement is recommended whenever the muffler is removed to ensure reliable performance and to reduce the risk of power loss or increased noise from a failing seal.

Typical Applications:
Used during exhaust system maintenance, muffler replacement, or top‐end repairs to restore a secure seal between the cylinder and muffler. Ideal for fixing exhaust leaks that cause loss of power, increased noise, fumes near the front cover, or soot deposits. Commonly fitted after impacts or vibration have disturbed the muffler joint, or whenever the muffler is removed for cleaning or inspection.
