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.

Sorry, we couldn't find any existing installation instruction that matched.
Pretty easy talking apart only (4) Allen nuts. pull out all parts carefully to remember how it goes back in. In reverse of taking it out. Grease everything good while installing after you clean it all first . With a little patience you are back in business.
In short. I removed all of the parts inside of the gun that looked worn or maybe causing an air leak. The parts diagram the ereplacements was a great help on putting the parts in the correct place. Thank you
