Alb Filter Flextube for refueling motorhomes with a hose connection. Are you familiar with the problem of a normal hose constantly lying on the ground and getting dirty when refueling? This is particularly annoying at filling stations with muddy ground or when it rains. The Alb Filter Flextube stays clean! When in use, simply pull the food-safe tube apart on the left and right and the bag remains fixed in the middle of the tube with a Velcro strip. The tube then simply retracts back into the bag and is stowed away compactly. The GEKA hose couplings with DVGW approval are compatible with Gardena hose connectors and are therefore suitable for use with a city connection or a tank lid that has a Gardena-compatible hose connector.
