This is Atlas Copco part number 3106967500 packing, stocked at Crowder Supply as AC-3106967500. It seals a pressure joint inside the rock drill, 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 shows up in the parts breakdown for the BBD 46 WS/WR Rock Drill. Check it against the reference number on the diagram first; serial breaks change what fits.
If you need the parts around it, the parts diagram hub has the full breakdown library, and the Atlas Copco lineup covers the machines themselves. Stocked in Denver orders placed by 4 PM ET ship the same day when the part is on the shelf.
