Ordering by number: this is 0663615100, the Atlas Copco O-Ring. 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.
You will find it on the diagram for the BBD 12D DS Rock Drill and BBD 15E ET Rock Drill, and on 1 other machine. Compare it to the reference callout on the diagram to be sure it is the position you need.
The rest of the assembly is on the same breakdown, and every diagram we publish is indexed on the full diagram library. It ships out of Denver, same day on in-stock orders placed before 4 PM ET.
