1 x Ball Valve (Tap). Rigid plastic 16mm Barbed Fitting allows water to flow through it from one hose pipe to another. On and off tap turns from side to side. Allows you to join your soaker hoses together wherever necessary. These plastic taps may be used in conjunction with other products in the same range such as barbed elbows, barbed end plugs, barbed straights, barbed tees, male hosetails, female tap adaptors, cross connectors, in-line-filters and pressure regulators which can also be purchased from our new online store as accessory packs or individually. Opening a series of Ball Valve Taps to different dilations around your irrigation system will help maintain consistency of flow rate.  Dip the end of the Soaker Hose into some hot water, then push the barbed fitting firmly into place. This forms a good water tight seal.
