The Rain Bird RD12SP45FN is a 12 in. RD1800-series pop-up spray head engineered for landscapes with fluctuating water pressure and steep slopes. It combines a SAM check valve, a 45 PSI PRS pressure regulator and Flow-Shield technology to deliver consistent coverage while preventing low-head drainage and misting.

  • 12 in. pop-up height; 16 in. body height; exposed diameter: 2 1/4 in.
  • Built-in Seal-A-Matic (SAM) check valve prevents low-head drainage; PRS maintains a regulated 45 PSI outlet.
  • Flow-Shield technology helps identify and diagnose blockage or abnormal flow quickly.
  • 1/2 in. female threaded inlet (NPT); compatible with Rain Bird nozzles including U-Series, MPR, HE-VAN, VAN and R-VAN rotary nozzles.
  • Durable UV-resistant plastic body with corrosion-resistant stainless steel internal parts for extended service life.
  • Nozzle not included — use manufacturer-recommended nozzles for correct radius and precipitation rate; recommended spacing 2.5–24 ft (0.8–7.3 m).
  • Non-potable cover indicated by a purple ring for reclaimed-water applications; designed for an operating range of 15–100 PSI.

Ideal for both residential and commercial irrigation, the RD12SP45FN delivers reliable pressure regulation and durable construction where dependable performance matters. Refer to Rain Bird technical brochures and nozzle performance charts for nozzle selection, installation and maintenance guidance.
