Ordering by number: this is Y31110030, the Tamco/Toku O-ring. It seals a pressure joint inside the chipping hammer, 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 is called out in the parts diagram for the THH 6 7 8 9 Chipping Hammer. Worth matching the reference number on the diagram against your own machine before you order the same part number can sit in more than one position.
The rest of the assembly is on the same breakdown, and every diagram we publish is indexed on the full diagram library. Stocked in Denver orders placed by 4 PM ET ship the same day when the part is on the shelf.
