Gasket is the Atlas Copco service part carried under part number 3121591200. 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 diagram library and the Atlas Copco lineup are the other two places to start. It ships out of Denver, same day on in-stock orders placed before 4 PM ET.
