Give plants consistent watering with the AccuFlow™ 1.0 GPH Pressure Compensating Emitter. The PC emitter is designed to deliver a constant output of 1.0 GPH of water whether the water pressure varies, and no matter the distance from the water source. Attach barbed inlet into the end of 1/4 in. feeder line (A220 and A250) and lift emitter with stake to keep off the dirt; or insert dripper 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. Emitter has a self-flushing feature to help eliminate sediments and reduce clogging. Emitter is made of polyethylene and silicone treated with UV inhibitors to prevent fading and cracking.
