Antelco have looked at the original and ever popular adjustable dripper and made it even better! There is now a brand new in-line option with a 4mm connection on each side so they can be quickly and easily joined together (with 4mm PVC micro irrigation pipe) to make a string of drippers, perfect for pots, containers and window boxes. With the flow rate adjustable from 0-33 litres per hour (2 litres per hour, per click) they are also ideal for controlling exactly how much water is applied, particularly important when irrigating large specimen trees and shrubs.
