Built for professional residential and commercial irrigation, the Hunter Pro-Spray PRS40 is a rugged, pressure-regulated spray body engineered to deliver consistent, efficient watering when used with MP Rotator nozzles. Its heavy-duty construction and maintenance-friendly design make it contractor-preferred.

  • Calibrated to regulate pressure at 40 PSI, optimizing MP Rotator performance and reducing misting and overspray.
  • Gray identification cap, co-molded chemical- and chlorine-resistant wiper seal, and no-leak cap design for reliable field performance.
  • FloGuard option limits flow to a low indicator stream if a nozzle is missing, preventing water waste and landscape erosion.
  • Optional factory- or field-installed check valve prevents low-head drainage; heavy-duty spring ensures consistent riser retraction.
  • Durable directional flush plug and interchangeable components simplify installation, service, retrofits, and upgrades on site.
  • Available models: shrub, 4", 6", and 12" pop-ups; standard 1/2" female inlet; operating pressure 15-100 PSI; 5-year warranty.

Specify the PRS40 when converting zones to MP Rotators or when system uniformity and water savings are priorities. Compatible with industry-standard female nozzles; MP Rotator nozzles sold separately.
