This is an authentic Craftsman replacement part. The metal piston ring is compatible with many chainsaw devices. This part has been designed to work as a seal between the piston and the engine\\\'s cylinder wall. If piston ring is broken or worn, it will cause gases to escape and enter the crankcase. In turn, this would create low compression and a decrease in power, possibly stalling out the engine. A set of wrenches, pliers and a screwdriver are needed in completing the repair. This item is sold individually.
