This is the Atlas Copco O-Ring part number 0663315202, also listed as 0663315200, Crowder SKU AC-0663315202. It seals a pressure joint inside the pump, 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 is called out in the parts diagram for the DOP 15N 15N US 15F Diaphragm Pump. It comes off the Atlas Copco DOP 15 Pneumatic Diaphragm Pump. 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.
The rest of the assembly is on the same breakdown, and every diagram we publish is indexed on the full diagram library. Stocked in Denver orders placed by 4 PM ET ship the same day when the part is on the shelf.
