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 rates are .5 and 1 GPH at 15 PSI. Available in packs of 10 and 25, these emitters are ideal for use with 1/4" 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.
Features
- Color-coded to easily identify flow rate
- The drip emitters can be installed where desired along the 1/4" micro tubing
- Ideal for a loop-type layout
- Turbulent flow through a labyrinth-water-passage design reduces likelihood of clogging
- Uniform flow rate at low pressure
- 1/4" barbed inlet and outlet for installation into 1/4" micro tubing
- Resistant to chemicals and fertilizers used in landscape applications
- Constructed of UV-resistant, durable plastic material to withstand the most adverse conditions
