O-Ring carries Atlas Copco part number 0663614000 and is stocked here under AC-0663614000. It keeps air or oil where it belongs inside the rock drill. Once it flattens or hardens, the machine loses pressure across the joint and performance falls off gradually rather than all at once.
The published breakdown lists it on the BBC 34DSI Rock Drill and ALF 67/80 67/80D Pusher Leg. 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 library 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.
