Jungheinrich uses flat-face hydraulic quick-release couplers on the mast. They're designed to prevent fluid loss and dirt ingress, so they don't match standard hose fittings (https://aerocomfittings.com/categories/hose-fittings). You'll need the OEM style or an ISO flat-face equivalent in the correct size, best to check with Jungheinrich or a supplier like Stucchi or Faster for the exact match.
