This is Atlas Copco part number 0663927900 O-Ring, stocked at Crowder Supply as AC-0663927900. 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 TEX 05PE Chipping Hammer. Check it against the reference number on the diagram first; serial breaks change what fits.
Everything else on that machine is one page away on the parts diagram hub; complete tools are on the Atlas Copco tool range. Stocked in Denver orders placed by 4 PM ET ship the same day when the part is on the shelf.
