Ordering by number: this is 9245996911, the Atlas Copco bumper – neoprene retainer. This part keeps the steel captive in the tool under repeated impact, so it is inspected at every steel change and replaced on condition rather than on a schedule.

The parts diagram hub is where to start if you are working back from a machine or send the model and serial and we will confirm it. Complete tools sit on the Atlas Copco catalog. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
