This is Chicago Pneumatic part number 9246020435 universal hose coupling – 1/2″, stocked at Crowder Supply as CP-9246020435. It makes the air or hydraulic connection to the tool. Thread and sealing-face condition here is the difference between full pressure at the tool and a slow leak nobody notices.

Give us the model and serial off your machine and we will confirm the fit; the full diagram library and the Chicago Pneumatic lineup are the other two places to start. Denver stock, with same-day shipment on in-stock orders in by 4 PM ET.
