the self-compensating adjustable in-line dripper - part of the gardena micro-drip-system - is particularly suitable for the irrigation of low plants with different water requirements. using the flow indicator on the dripper it is possible to set the required amount of water. in this way, 1 to 8 liters of water can be supplied per hour. the in-line dripper is self-compensating (from 1 to 4 bar), thus ensuring a homogeneous distribution of water - regardless of pressure. thanks to the self-cleaning labyrinth membrane, reliable and long-lasting operation is guaranteed. the patented "quick & easy" connection technology allows easy connection to the 4.6 mm (3/16 ") branch pipe. five drippers and a cap are supplied.
