The Rain Bird XB-20 is a professional-grade pressure-compensating (PC) emitter engineered to deliver a precise and consistent flow of 2.0 gallons per hour (7.6 L/h). Designed for larger landscape plants, it ensures that every tree and shrub receives the exact amount of water required, even with varying inlet pressures or changes in elevation. The "Xeri-Bug" design includes a self-flushing action that allows small debris to pass through the emitter, significantly reducing the risk of clogging and ensuring long-term reliability. Color-coded in red for quick flow rate identification, the XB-20 is manufactured from highly durable, UV-resistant materials to withstand harsh outdoor conditions and chemical exposure. Ideal for residential and commercial drip irrigation systems, it provides an efficient and water-wise solution for maintaining a healthy landscape with minimal maintenance
