Supply water directly to your plants with ¼ in. distribution tubing. Attach tubing to the main line to create a feeder line that delivers water to a low-flow, drip-watering device, or use as a main line in a smaller drip system. The quarter-inch tubing, also known as micro tubing or spaghetti tubing, has an outside diameter (OD) of 0.250 in. and internal diameter (ID) of 0.170 in. While other manufacturers use blended recycled material to construct their entire tubing, Raindrip poly tubing is engineered in layers for durability using 100% virgin content for its outer and inner layers, with 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.
