DIG's 1/4 in polyethylene micro tubing is available in coil lengths of 50, 100, and 500 feet. This commercial grade polyethylene micro tubing (Distribution tubing) is made of high quality linear low-density polyethylene resin. The micro tubing is manufactured with an antioxidant and contains 2% concentrated Carbon Black to protect the finished product from thermal degradation. The micro tubing is used in a wide range of drip irrigation layouts, including being used as feeder lines from the 1/2 in. drip tubing to extend drip emitters or micro sprinklers to the plants, as extensions from the 4, 6, and 12-outlet drip manifolds, or as the supply line for a complete 1/4 in. drip system.
