This is American Pneumatic Tool part number 1280582693 the number that superseded 18753 lower valve seat, stocked at Crowder Supply as APT18753. It directs the flow that reverses the piston in the clay digger. Valve wear changes port timing, and the machine loses blow rate before it loses the ability to run.
Crowder’s breakdowns list this part on the 118 Clay Digger and 119 Trench Digger, and on 1 other machine. That machine is the APT 117 Pneumatic Paving Breaker if you are pricing a replacement rather than a repair. Pull up the diagram and confirm the reference number for your serial before ordering.
Work through the rest of the assembly on the same breakdown, or start over from the full diagram library. Denver stock, with same-day shipment on in-stock orders in by 4 PM ET.
