This is Atlas Copco part number 0663212000 O-Ring, stocked at Crowder Supply as AC-0663212000. It seals a pressure joint inside the breaker, and because elastomer takes a set long before the metal around it wears, it is one of the first items to replace when a machine starts weeping air or oil.
It is called out in the parts diagram for the TEX 140P PS Paving Breaker and BBD 94W 94WS 94WE Rock Drill, and on 2 other machines. Compare it to the reference callout on the diagram to be sure it is the position you need.
If you need the parts around it, the full diagram library has the full breakdown library, and the Atlas Copco catalog covers the machines themselves. Denver stock, with same-day shipment on in-stock orders in by 4 PM ET.
