This dripper is suitable - within the Micro-Drip-System - for the selective irrigation of single plants or longer plant rows with similar water requirements, e.g. hedges. The water application rate is approx. 2 litres per hour. For watering single plants, the end dripper is screwed into the end of the 4.6 mm (3/16") distributor pipe. The 13 mm (1/2") installation pipe can be perforated with a mounting tool and the end drippers can be mounted directly. Included in delivery are 25 drippers and a cleaning needle. The cleaning needle is used for easy cleaning of a dirty dropper.
