Ordering by number: this is 3081602063, the Chicago Pneumatic O-Ring. It keeps air or oil where it belongs inside the tool. Once it flattens or hardens, the machine loses pressure across the joint and performance falls off gradually rather than all at once.
Give us the model and serial off your machine and we will confirm the fit; the full diagram library and the Chicago Pneumatic tool range are the other two places to start. Denver stock, with same-day shipment on in-stock orders in by 4 PM ET.
