O-Ring is the Chicago Pneumatic service part carried under part number 4700W65112. Seals like this one are consumables in a tool they are cheap, they age with heat and hours, and replacing the whole set during a teardown saves a second strip-down later.
If you are working from a machine rather than a part number, start at the parts breakdown index, or send us the model and serial and we will match it. Machines themselves are on the CP tool catalog. It ships out of Denver, same day on in-stock orders placed before 4 PM ET.
