O-ring carries American Pneumatic Tool part number 1280582756, which replaced the older number 00566 and is stocked here under APT566. It seals a pressure joint inside the breaker, and because elastomer takes a set long before the metal around it wears, it is one of the first items to replace when a machine starts weeping air or oil.
The published breakdown lists it on the 180 Paving Breaker and 190 Paving Breaker, and on 5 other machines.
The rest of the assembly is on the same breakdown, and every diagram we publish is indexed on the parts diagram hub. Denver stock, with same-day shipment on in-stock orders in by 4 PM ET.
