This is the American Pneumatic Tool air inlet swivel part number 1280582665, previously 17951, Crowder SKU APT17951. It joins the hose to the machine. Connection hardware gets dragged, dropped, and cross-threaded, so it is a common replacement.
You will find it on the diagram for the 140 Paving Breaker and 140A Airgo Paving Breaker, and on 1 other machine. That machine is the APT 140 Pneumatic Paving Breaker if you are pricing a replacement rather than a repair.
Work through the rest of the assembly on the same breakdown, or start over from the full diagram library. Stocked in Denver orders placed by 4 PM ET ship the same day when the part is on the shelf.
