The Orbit 1/2" distribution tubing is a great way to get water exactly where you need it. This tubing can be installed both above and below ground and will distribute water directly to your plants. This tubing is “blank” which means it is a continuous run of tubing without any pre-installed emitters in it. Use a Drip Punch Tool to insert 1/4" barb drip fittings or emitters at points close to each plant. Since the outside diameter of 1/2-inch tubing may vary by manufacturer, we recommend using Orbit Universal Drip Fittings when connecting to non-Orbit drip systems. We also strongly recommend using a 2-in-1 filter and pressure regulator for all drip zones. For non-constant pressure outdoor irrigation use with cold water only. Packaged dimensions: 3" x 17" x 17"
