This replacement piston ring is an authentic OEM sourced component which is specially produced for use with Tanaka gas-powered lawn and garden equipment. A worn or a 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 run at all. Please note this high-quality part is made of durable metal and it is sold individually.

Fool me once, shame on you, fool me twice, shame on me
These rings had too much slop, they were slightly larger than the piston. Not sure why because it was the required part number. Needless to say, they both broke.
