This is the Atlas Copco O-Ring part number 0663614400, Crowder SKU AC-0663614400. 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 shows up in the parts breakdown for the DOP 15N 15N US 15F Diaphragm Pump. That machine is the Atlas Copco DOP 15 Pneumatic Diaphragm Pump if you are pricing a replacement rather than a repair. Pull up the diagram and confirm the reference number for your serial before ordering.
