O-Ring is the Chicago Pneumatic service part carried under part number P092091, cross-referenced to 3310104232. It seals a pressure joint inside the rivet buster, 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.
It shows up in the parts breakdown for the TEX 626 RP & RD Rivet Buster and CP 4129 Chipping Hammer, and on 2 other machines.
The rest of the assembly is on the same breakdown, and every diagram we publish is indexed on the parts diagram library. Denver stock, with same-day shipment on in-stock orders in by 4 PM ET.
