I bought the stainless steel hose clamps, the blue drinking water hose, the DOMETIC plastic hose connectors and the MAESTRINI hose nozzles AG, brass from SVB. After commissioning, water immediately sprayed out of all the connections. I then fitted an old hose clamp from the hardware store to one connection - it was completely leak-proof!!! The hose clamps are specified for a hose thickness of 16 - 27mm. The drinking water hose is 21mm and one suction hose is 25mm. The stainless steel clamps are much too hard and deform very unevenly when tightened. As a result, the hose is not pressed evenly around the nozzle. Conclusion: The hose clamps are completely unsuitable for drinking water hoses. I am now getting cheap, flexible hose clamps from the hardware store that work.
