Deliver water precisely to your plants with OE in. distribution tubing. Use the OE in. supply tubing as a feeder line to branch off the main line & supply water to a low-flow, drip-watering device, or as a main line in a smaller drip system. Tubing outside diameter (OD) is 0.250 in., internal diameter (ID) is 0.170 in.; works with new and existing systems. Also known as micro tubing and spaghetti tubing, OE in. tubing is made of vinyl treated with UV inhibitors. Unlike other manufacturers that use blended recycled material for their tubing, Raindrip vinyl tubing is constructed with 100% virgin content for a more durable product. 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.
