Full details

The ECSiNG exhaust gasket 4-pack is an essential maintenance component designed for professional arborists and DIY enthusiasts who own Husqvarna chainsaws. These gaskets provide a reliable, airtight seal between the cylinder deflector and the muffler to prevent dangerous gas leaks and maintain engine back pressure, though they must be installed with care to ensure the seating surfaces are clean to guarantee a proper fit.
