Water plants precisely where they need it most—the root zone—with the 4.0 GPH Take-a-Part™ Flag Emitter. Ideal for watering individual shrubs, trees & plants in containers and hanging baskets, creating good soil moisture plants need for optimal growth and overall health. The color-coded flag identifies the GPH the emitter delivers and makes the dripper easier to grasp and position; however, it does not adjust the water flow. Pull the flag to take the emitter apart for cleaning. 1/4 in. insert barb connects emitter to end of micro tubing or into a punched hole in the supply line. Made of polyethylene treated with UV inhibitors to prevent fading and cracking
