This is an authentic replacement part manufactured for use with brush cutters and trimmers. The piston ring is used to form separate the combustion chamber and the crankcase. The piston ring prevents combustion gases from entering the crankcase. A broken or damaged piston ring will allow the combustion gases to enter the crankcase which will cause a reduction of compression and a loss of power. This piston ring is sold as an individual replacement part.
This is an authentic Hitachi replacement part that has been sourced from the original manufacturer to be used with blowers and trimmers. The ring fits over the piston and is used with the oil to form a seal between the wall of the cylinder and the piston. The seal separates the combustion chamber and the crankcase. Damage to the ring can cause the seal to be broken allowing gasses to escape the cylinder and this can lead to a loss of compression. The piston ring is available as an individual replacement part, please see illustrated diagram for associative parts.
