O-Ring is the Atlas Copco service part carried under part number 3371820748. 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.
The published breakdown lists it on the BRK 95 95VR 95HBP Hydraulic Paving Breaker and PDR 95T 95RV Hydraulic Post Driver, and on 3 other machines. Pull up the diagram and confirm the reference number for your serial before ordering.
Everything else on that machine is one page away on the parts diagram library; 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.
