4" 1800 Series Spray Heads
All models feature Rain Bird's patented pop-up mechanism with heavy-duty stainless steel spring for dependable out-of-sight retraction, plus an exclusive co-molded wiper seal for unmatched resistance to grit, pressure, and extreme environments.
The Perfect Pair for Pressure Regulation
Rain Bird’s pressure-regulating stem (PRS) saves up to a gallon of water per minute.
We offer three perfectly paired combinations of PRS spray bodies and high-efficiency nozzles. Each pair is designed to work together to give you the best possible performance across your entire irrigation system — all while saving water.
