Deliver a steady output of water to each plant with the 2.0 GPH Pressure Compensating Emitter. The PC emitter maintains a constant flow rate of 2.0 GPH in varying water pressure changes and positioned at any spot along supply tubing. Barbed inlet inserts into the end of 1/4 in. feeder line (A220 and A250); dripper can be lifted up using a stake to keep it off the dirt, or 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 emitter eliminates sediments inside to reduce clogging. Emitter is made of polyethylene and silicone treated with UV inhibitors to prevent fading and cracking.
