This is American Pneumatic Tool part number 1280583799, which replaced the older number 02601 rubber packing, stocked at Crowder Supply as APT2601. Its job is to hold the pressure boundary between two mating faces; a hardened or nicked seal shows up as lost power and a damp housing well before anything else fails.
It shows up in the parts breakdown for the 137 Rock Drill. The complete machine is the APT 137 Pneumatic Rock Drill. Check it against the reference number on the diagram first; serial breaks change what fits.
The rest of the assembly is on the same breakdown, and every diagram we publish is indexed on the parts diagram hub. Stocked in Denver orders placed by 4 PM ET ship the same day when the part is on the shelf.
