O-Ring carries Atlas Copco part number 3371817701 and is stocked here under AC-3371817701. It keeps air or oil where it belongs inside the rock drill. Once it flattens or hardens, the machine loses pressure across the joint and performance falls off gradually rather than all at once.
It appears on the LHD 23M Hydraulic Rock Drill and RDR 48R Rock Drill, and on 1 other machine breakdown. 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 diagram library; complete tools are on the Atlas Copco lineup. Denver stock, with same-day shipment on in-stock orders in by 4 PM ET.
