Ordering by number: this is 1280582635, which replaced the older number 17856, the American Pneumatic Tool valve lever spring. This is control gear it meters air to the tool. A worn control gives creep, hard starting, or a tool that will not shut off cleanly.

Give us the model and serial off your machine and we will confirm the fit; the full diagram library and the APT lineup are the other two places to start. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
