This is American Pneumatic Tool part number 1280583530, which replaced the older number 03531 air inlet swivel nut, stocked at Crowder Supply as APT3531. It joins the hose to the machine. Connection hardware gets dragged, dropped, and cross-threaded, so it is a common replacement.
Crowder’s breakdowns list this part on the 115 Rock Drill. It comes off the APT 115 Pneumatic Rock Drill. Compare it to the reference callout on the diagram to be sure it is the position you need.
Work through the rest of the assembly on the same breakdown, or start over from the parts breakdown index. Denver stock, with same-day shipment on in-stock orders in by 4 PM ET.
