Cylinder Cap is the American Pneumatic Tool service part carried under part number 1280582343, which replaced the older number 18391. The cylinder is the bore the piston runs in, and it sets the working clearance of the tool once the bore opens up, air bypasses the piston and blow energy drops.

The parts breakdown index is where to start if you are working back from a machine or send the model and serial and we will confirm it. Complete tools sit on the American Pneumatic Tool range. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
