Needle Attachment Spring, American Pneumatic Tool part number 1280582354, which replaced the older number 18402, listed at Crowder Supply as APT18402. Springs in a tool fatigue with cycle count rather than age, so a control that has gone lazy or fails to return is usually this part rather than the component it drives.

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