A great all-around hose. It has 5/8" outside diameter with a 1/2" inside diameter. This hose will perform up to 200' runs. If you need a longer run, we recommend the OS series, but remember OS series is a slow weeper.The double thick side wall allows more even water distribution: The 250' is standard with no ends. The Pro Series is kink and crush resistant and will not freeze. We recommend that you either cover the hose with mulch or bury it up to 6" deep for longest life. Typically irrigates a 2' wide strip, depending on the type of soil it is used on.
