Pressure Spring is the Atlas Copco service part carried under part number 3121078800. Springs in a tool fatigue with cycle count rather than age, so a control that has gone lazy or fails to return is usually this part rather than the component it drives.
Give us the model and serial off your machine and we will confirm the fit; the parts diagram library and the Atlas Copco catalog are the other two places to start. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
