Ordering by number: this is 0663614200, the Atlas Copco O-Ring. 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.
The published breakdown lists it on the BBD 94W 94WS 94WE Rock Drill. Pull up the diagram and confirm the reference number for your serial before ordering.
The parts diagram hub indexes every breakdown we publish, and the Atlas Copco lineup has the tools these parts go into. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
