Expand your drip irrigation system easily with the preassembled 5/8 in. supply tubing. The distribution tubing comes with a hose thread swivel adapter on one end to connect to the water source, and also includes an end plug. The 5/8 in. supply tubing has an outside diameter (OD) of 0.700 in. and 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 more durable product, 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.
