Ordering by number: this is 3377000533, the Atlas Copco O-Ring. It keeps air or oil where it belongs inside the drill. Once it flattens or hardens, the machine loses pressure across the joint and performance falls off gradually rather than all at once.
You will find it on the diagram for the COR 5/15 Hydraulic Core Drill and MHC5 Hydraulic Core Drill, and on 1 other machine. 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 on the parts breakdown index; complete tools are on the Atlas Copco tool range. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
