Cylinder Ring & O-Ring Kit #05C126

Air compressor cylinder ring and o-ring kit. Includes compression ring, head o-ring, and valve plate o-ring. 

This tends to be a high-wear part, especially if you are in a high-particulate environment.

Pro Tip: Order the cylinder when buying this part as the two wear together. 

Note: After you install the ring on the piston rod, install the rod in the cylinder by inserting the rod from the top of the cylinder and pull it down. Do not push the rod into the cylinder from the bottom!
