DIG Inline Drip Emitters offer flexibility and simplify the installation for residential drip irrigation systems. Their rate of flow depends on the inlet pressure; with higher pressure the flow will increase, with lower inlet pressure, it will decrease. The drip emitters’ nominal flow rate is 1 GPH at 15 PSI. These emitters are ideal for use with ¼” micro tubing as the main line in pots, baskets, planter boxes, vegetable gardens and for low-pressure gravity feed systems. Install the drip emitters “inline” as needed in any spacing with the 1/4″ micro tubing as the main line.
