DIG Irrigation PCO-020 PC Self-Flushing 2 GPH Button Drip Emitter

DIG Pressure Compensating (PC) Button Drip Emitters are designed to produce a consistent flow rate over a pressure range of 7.25 to 58 PSI. DIG PC drip button emitters are continuously adjusting to varying water pressures, ensuring a constant flow from each drip emitter regardless of pressure fluctuations or varying elevations along the line. The PC drip emitters are available in .5, 1, 2 and 4 GPH. Used for flowers, shrubs groundcovers and trees, DIG PC drip emitters offer a convenient way to water both, new and existing landscapes, including difficult terrain such as slopes, oddly shaped areas and sites with high winds.
