Drip line is durable, economical, and very so easy to use. Our 1/4" drip line has 1/2 GPH emitters built right in. Available in varying emitter spacings to meet all your needs. This commercial grade, non pressure compensating poly drip line is made of the highest quality resins and is resistant to UV rays. This tubing is great for using in your raised beds, window boxes, garden rows (under 30'), and densely planted landscape areas. Many use it for square foot gardening and making tree rings also. This drip line also works well with gravity and low-pressure drip systems as long as the water is clean and filtered, and a minimum of 5 PSI can be achieved.Please note: If using the closer 6" or 9" emitter spacing dripline you will get better more uniform flow rates if you keep the dripline run lengths to 18 feet or less. Higher flow in the small micro-tubing creates more friction so higher pressure loss is experienced in the longer runs. This results in lower flow from the emitters farther down the line.To Install 1/4" Drip Line Punch a hole into mainline tubing using any of our 1/4" punches. Next, install a 1/4" barbed coupler into the section of drip line and insert the other end of the barbed coupler into the hole that was punched in mainline. Then, plug the open end of the drip line with a goof plug.
