Ordering by number: this is 1310034211, the Chicago Pneumatic ball coupling – 2″. It joins the hose to the machine. Connection hardware gets dragged, dropped, and cross-threaded, so it is a common replacement.

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 CP tool catalog. Denver stock, with same-day shipment on in-stock orders in by 4 PM ET.
