Ordering by number: this is 9245998740, the Atlas Copco 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 parts breakdown index and the Atlas Copco catalog are the other two places to start. Stocked in Denver orders placed by 4 PM ET ship the same day when the part is on the shelf.
