Check the listing for details. Tempo Inline Dripper. Condition: New. Listed at 10.36 USD. Inline Drippers have two barbed connections and are designed for use with 1/4" micro tubing (.170" ID x .250" OD) to create a run of drippers by installing in-line and then plugging the end of the run with a 1/4" goof plug. The drip point is located in the flat disc center of the emitter. Creating a ring is also a great way to water trees or larger shrubs. Ideal for anywhere you want a consecutive run of drippers on one line of 1/4" micro tubing. Different flow rate emitters can be mixed in the same run to meet all your watering needs as long as you do not exceed the capacity (30 GPH) of the 1/4" micro-tubing. *Tubing in images is for display purpose only, not included with dripper.
