The Hunter PR-075 pressure regulator reduces high inlet pressure to a factory-set 45 PSI to protect rotor sprinklers and improve nozzle performance. Compact and reliable, it maintains steady pressure so nozzles operate at peak efficiency while reducing water waste.

  • Factory-set to 45 PSI - reduces incoming pressures (typically 50-100 PSI) to a consistent 45 PSI for rotor operation.
  • Fits 3/4 in inlet and outlet connections - designed for use under 3/4 in rotor sprinklers and risers.
  • Flow range 1.5-8.0 GPM - supports common rotor nozzle flows without restricting performance.
  • Compact inline design - overall height about 2.25 inches, installs below the rotor or inline with riser fittings.
  • Improves efficiency and protection - helps nozzles run at design pressure and can save up to 25% water in some systems.

Easy to install into standard 3/4 in threaded fittings, the PR-075 is an effective, low-cost way to stabilize pressure at the sprinkler head and extend the life of system components. Confirm compatibility with your rotor model and local distributor for availability.
