Beige micro drip irrigation tubing is used as a feeder line from the 1/2" poly tubing (main line) to the plants. It's color gives you the ability to match the color of your project or surroundings. It may also be used as the basis for a complete system for containers and patio plants. Maximum working pressure for the micro tubing is 60 PSI, but we recommend running your drip irrigation or soaker hose system around 25 psi. Maximum flow rate is 30 GPH. Micro tubing is .160 ID and .250 OD.
