Give plants consistent watering with the 1 GPH Pressure Compensating Dripper. PC emitters are designed to deliver the same output of water, whether water pressure varies, or where the emitter is placed on tubing. The turbulent flow emitter flushes out sediments to reduce clogging. Connects to 1/4 in. tubing or attaches directly into 1/2 in., 5/8 in., or 0.710 in. supply tubing. Ideal for watering individual shrubs and trees in landscapes, and plants in container pots and hanging baskets. Dripper is made of polyethylene and silicone treated with UV inhibitors.
