This is Atlas Copco part number 3121080400 plug, stocked at Crowder Supply as AC-3121080400. It closes a port or passage in the tool. Small, but a plug that will not seal turns into a leak that is hard to trace.
Give us the model and serial off your machine and we will confirm the fit; the parts diagram hub and the Atlas Copco catalog are the other two places to start. Denver stock, with same-day shipment on in-stock orders in by 4 PM ET.
