O-Ring carries Chicago Pneumatic part number 3081600988 and is stocked here under CP-3081600988. 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. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
