Rain Bird Drip Irrigation Installation Tool secures tubing and emitters to water plants individually. It provides a 1-step installation of drip emitters, goof plugs, and 1/4 inch barbed insert fittings. The notch on the side makes it simple to remove fittings, emitters, and goof plugs. The hole on top of the handle is used to insert goof plugs to close gaps in the tubing. This emitter installation tool works with drip tubing that is 1/2 inch or 3/4 inch in diameter. The purple color emitter tool helps you add supplemental watering to individual plants.
