Button Drip Emitters 1GPH Bag of 5

Button drippers with turbulent flow, which slows the velocity of the water to provide a predetermined flow rate at a preset pressure. Turbulent flow drippers regulate water flow by dissipating energy in friction against the walls of the labyrinth like water passage. Button drippers will provide the suggested flow rate at the recommended pressure of 25 PSI, and as the pressure increases so will the flow.
