This is an authentic OEM sourced replacement component which is specially designed for use with Homelite and Ryobi handheld lawn and garden equipment. A worn or broken piston ring will allow combustion gasses 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 run at all. Keep in mind this high-quality part is made of durable metal and is sold individually.

Perfect Replacement rings
These piston rings were exactly the right ones necessary to repair an older John Deere S1400 - aka (Homelite UT 20810) string trimmer. They arrived in a few days and where of excellent quality, and it was just a matter of following the piston replacement videos to guide me through the repair.
Thank you.
