Dust Seal is the Atlas Copco service part carried under part number 3376100721. It seals a pressure joint inside the 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.
The published breakdown lists it on the COR 5/15 Hydraulic Core Drill and MHC5 Hydraulic Core 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 parts diagram hub. It ships out of Denver, same day on in-stock orders placed before 4 PM ET.
