Piston Ring 503289010

This is an authentic OEM sourced replacement part which is specially designed for Husqvarna lawn and garden equipment. The piston rings are generally utilized to seal the space between the piston and the cylinder. This seal separates the combustion chamber and the crankcase to prevent gasses from entering the crankcase which can cause a loss of compression and can shut down the engine. Unfortunately, over time the material may wear out and begin to fail eventually requiring a replacement. Keep in mind this high-quality piston ring is made of durable metal and is sold individually.
