Build your drip system with durable tubing to transport water to your plants. 5/8 in. distribution tubing works as a main line to deliver water to an emitter or a feeder line; or punch emitters into side of tubing to distribute moisture along the line. The 5/8 in. supply tubing has an outside diameter (OD) of 0.700 in., internal diameter (ID) of 0.600 in. While other manufacturers use blended recycled material for their entire tubing, Raindrip poly tubing is constructed with an innovative layering method, using 100% virgin content for both inner and outer layers for a durability, and a 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. Raindrip is a leading manufacturer of drip and micro-irrigation solutions and the trusted brand of landscapers since 1972. Build, expand, or repair your system with our rigorously tested products designed to save you time and money.
