Is the Quick connector DN5.5 without valve, with hose socket, hardened zinc-plated steel, 1100 series compatible with 1100N series couplings under 30 bar working pressure?

No. Quick connector DN5.5 without valve, with hose socket, hardened zinc-plated steel, 1100 series is not compatible with 1100N series couplings. The product description explicitly states that couplings of series 1100 should not be combined with series 1100N. Although both are rated for the same working pressure (30 bar) and share similar intended use and materials, the manufacturer warns against mixing the two series.
