O-Ring is the Atlas Copco service part carried under part number 0663212200 (also carried as 9232120180). It keeps air or oil where it belongs inside the breaker. Once it flattens or hardens, the machine loses pressure across the joint and performance falls off gradually rather than all at once.
It is called out in the parts diagram for the Red Hawk Gas Breaker/Drill and BBD 46 WS/WR Rock Drill, and on 3 other machines. Compare it to the reference callout on the diagram to be sure it is the position you need.
