Splash-free filling - The angled filling opening with intelligent water guidance enables precise filling without splashing, simplifying the freshwater supply for motorhomes with ergonomic operation and minimal effort. Temperature compensation - Specially developed material behavior automatically compensates for thermal expansion differences, prevents stress cracks, and preserves the sealing function. Complete with 2 keys - An innovative backup system with two individual keys prevents operation interruptions in case of loss and guarantees easy ongoing access to the water valve for mobile freshwater supply. Use scenarios - On the road during camping trips: ensures a clean, reliable water fill and secure protection against contaminants while traveling and at campsite connections. - Remote camping or outdoor events: allows splash-free filling and quick access to the water valve, reducing setup time and water handling effort. - In locations with temperature variation: temperature compensation maintains seal integrity and durability when ambient temperatures fluctuate.
