This is Chicago Pneumatic part number 3377000660 engine half coupling, stocked at Crowder Supply as CP-3377000660. 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 LP 18-2×20/1×40 Twin PE Hydraulic Power Pac and PAC P18 Twin E11 Twin Hydraulic Power Pac. The tool itself is the Atlas Copco LP 18 Twin Hydraulic Power Pack. Pull up the diagram and confirm the reference number for your serial before ordering.
