This is Tamco/Toku part number Y10219170 O-ring, stocked at Crowder Supply as TK-Y10219170. It keeps air or oil where it belongs inside the chipping hammer. Once it flattens or hardens, the machine loses pressure across the joint and performance falls off gradually rather than all at once.
You will find it on the 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 parts diagram library. Denver stock, with same-day shipment on in-stock orders in by 4 PM ET.
