Get precise, even watering right to your plant’s root zone with the AccuFlow™ 0.5 GPH Pressure Compensating Emitter. The PC emitter maintains a constant flow of 0.5 GPH—even when the water pressure varies. The dripper with self-piercing barb can be attached to the end of 1/4 in. feeder line (A220 and A250) and raised with a stake to keep off dirt, or inserted into a punched-out hole in tubing to water plants along the run. Ideal for watering landscape and container plants, shrubs, trees, and hanging baskets. The self-flushing emitter cleans out sediments to minimize clogging. Emitter is made of polyethylene and silicone treated with UV inhibitors to prevent fading and cracking.
