Product Description

This piston ring is an authentic manufacturer-approved replacement part, it is specially made for use on Ryobi chainsaws. The purpose of a piston ring is to create an air-tight seal inside the cylinder. A worn or broken piston ring will allow combustion gases to escape the seal and enter the crankcase. This would cause low compression and a loss of power, replacing an o-ring should resolve this issue. It is made of durable metal and it is sold individually.
