Air Compressor Piston Ring #01A7C5

2 HP Piston ring for air compressors. This tends to be a high wear part, especially if you are in a high particulate environment. Order the cylinder sleeve when buying this part as the two wear together.

Important: This part is for newer models with motor Serial # ending in "-O". If you have an older model not ending in "-O", order MP2009-CAT instead. 

Extra Details

NOTE: The piston ring will be flat, and once placed on the pinch plate and tightened, it will form to shape once it starts moving up and down inside the cylinder cup.
