DIG - 4 GPH Pressure Compensating Drip Emitter - PCO-040

4 GPH Pressure Compensating 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. 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. Specifications Flow rate and color code: 4 GPH (15.5 L/H) Color Code – Red Operating pressure: 7.25 - 58 PSI (.5 - 4 BAR) Inlet size: 1/4" (4 mm) barb Outlet size: 1/4" nipple  Filter requirement: 150 mesh/100 microns for 1 GPH (3.8 L/H) or higher Filter selection depends on water quality and concentration of dirt particles Materials: Body and cover: polypropylene Diaphragm: silicone Features Labyrinth water passage with a floating silicon diaphragm design provides a self-cleaning mechanism at the water outlet Barbed inlet for installation into drip tubing or 1/4″ distribution tubing Male nipple outlet for a placement of multi-outlet adapter or bug caps Constructed of UV-resistant, durable plastic material to withstand the most adverse conditions Available in four color-coded flow rates for easy identification Pressure compensation enables the use of longer laterals with smaller diameter tubing Ideal watering solution for long laterals, rapid irrigation cycles, and for light soils Outlet can be connected into 1/8″ micro tubing with a stake for branching from the main line or lateral Unaffected by fluctuating inlet water pressure
