Count on the same, consistent output of water delivered to each plant with the 5.0 GPH Pressure Compensating Emitter. The PC emitter maintains a constant flow rate of 5.0 GPH even when the water pressure changes. Connect the barbed inlet on the emitter into the end of 1/4 in. feeder line (A220 and A250) and lift the emitter off the dirt using a stake; the emitter can also be attached directly into a punched-out hole in supply tubing to water plants along the run. Ideal for watering landscape and container plants, shrubs, trees, and hanging baskets. The self-flushing dripper cleans out sediments to prevent clogging. Emitter is made of polyethylene and silicone treated with UV inhibitors to prevent fading and cracking.
