Made of high-quality vinyl, the micro tubing is flexible and relatively soft. It is manufactured with an antioxidant and contains a minimum of 2% concentrated carbon black to protect the finished product from thermal degradation. The vinyl micro tubing is used in a wide range of drip irrigation applications, including 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.
