Piston Ring 503289014

This replacement piston ring is supplied directly from the original equipment manufacturer for use with Husqvarna chainsaws. It is used to create an air-tight seal between the piston and the cylinder walls, a worn or broken piston ring will allow combustion gases to escape the seal and enter the crankcase, causing low compression and a loss of power. If compression is reduced significantly, the engine will not run at all. Please note this high-quality metal ring is sold individually.
