O-Ring, Chicago Pneumatic part number 4700W65024, cross-referenced to 0663213300, listed at Crowder Supply as CP-4700W65024. It seals a pressure joint inside the tool, and because elastomer takes a set long before the metal around it wears, it is one of the first items to replace when a machine starts weeping air or oil.
Give us the model and serial off your machine and we will confirm the fit; the full diagram library and the CP tool catalog are the other two places to start. It ships out of Denver, same day on in-stock orders placed before 4 PM ET.
