This is an authentic OEM sourced replacement piston ring, it is commonly utilized with Ridgid framing nailers. 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 be able to run at all. This high-quality part is made of durable plastic and is sold individually.
