Rain Bird Drip Emitter are used to irrigate individual plants and trees. You can vary how much water you provide any given plant by installing drippers with different flow rates. Drippers can be installed:
directly into the blank 16mm irrigation pipe
or on a stake which is attached using 6mm distribution tubing
4 litre-per-hour pressure compensating dripper. This dripper is BLACK.
4mm Barbed inlet for easy installation into thinwall polypipe.
Pressure compensating means that regardless of the incoming pressure, the dripper will maintain its flow rate of 3.8 litres per hour (minimum pressure 1.5 bar for compensation to commence).
