Description
Overview:
This is a genuine Husqvarna exhaust gasket for petrol chainsaws, designed to seal the exhaust outlet on the cylinder to the exhaust system and stop gases escaping. Made from a durable, heat‐resistant composite, it maintains a tight seal under vibration and temperature changes, helping the saw run efficiently and reducing the risk of hot gas leaks damaging nearby components. It is suitable for Husqvarna 300‐series saws and is commonly used on models such as the 340 and 345. The gasket is an OEM part, supplied to the original specification for reliable fit and performance. Manufacturer Part Number (MPN): 503862501. A sound exhaust seal supports stable power delivery, cleaner operation, and protects the cylinder and exhaust joint during routine cutting work.
