This is American Pneumatic Tool part number 1280583474, listed as 02266 before the renumbering O-ring seal – #2-013, stocked at Crowder Supply as APT2266. 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.
If you are working from a machine rather than a part number, start at the full diagram library, or send us the model and serial and we will match it. Machines themselves are on the American Pneumatic catalog. It ships out of Denver, same day on in-stock orders placed before 4 PM ET.
