This is the Atlas Copco seal part number 0665099938, Crowder SKU AC-0665099938. It seals a pressure joint inside the pusher leg, 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.
The published breakdown lists it on the ALF 71 71-1 Pusher Leg. It comes off the Atlas Copco Pusher Leg Attachment For BBC Series Rock Drills. Worth matching the reference number on the diagram against your own machine before you order the same part number can sit in more than one position.
Everything else on that machine is one page away, and the parts diagram hub indexes every breakdown we publish. Denver stock, with same-day shipment on in-stock orders in by 4 PM ET.
