Ordering by number: this is 470W254090, the Chicago Pneumatic trimming spacer. It absorbs shock between two components of the tool, protecting the parts on either side of it from metal-to-metal contact.

If you are working from a machine rather than a part number, start at the parts diagram library, or send us the model and serial and we will match it. Machines themselves are on the CP tool catalog. Stocked in Denver orders placed by 4 PM ET ship the same day when the part is on the shelf.
