Product Description Use the ½ in. distribution tubing to transport water directly to your plants. Works as a supply line to an emitter or a feeder line branching off larger tubing or pipe. Another use is to punch emitters directly into the side of the tubing to deliver water along the way. The ½ in. tubing features an outside diameter (OD) of 0.620 in. & internal diameter (ID) of 0.520 in. While other manufacturers use blended recycled material to construct their entire tubing, Raindrip poly tubing has a unique layering method using 100% virgin content for the outer and inner layers for a more durable product, and middle layer of recycled content. Drip irrigation systems are easy to customize, install, and operate. As part of a complete system, the supply tubing transports water to the area to be irrigated. Drip irrigation gradually and evenly waters the root zone of your plants, keeping it moist but never saturated with water. Your plants maintain the ideal balance between water and air for optimal growth and overall health.
