The Irritrol IPN-12H I-PRO fixed nozzle delivers reliable, efficient irrigation for half-circle areas up to 12 feet. Engineered with Matched Precipitation Rate (MPR) technology and an integrated filter, the IPN-12H provides uniform water distribution to reduce runoff and over-watering.

  • Coverage radius: 12 ft (color-coded brown for quick identification).
  • Arc: 180° half-circle; trajectory: 23° for consistent spray placement.
  • Thread/inlet: 1/2" female thread; fits standard male-threaded risers.
  • Matched Precipitation Rate (MPR) for even coverage across arc family.
  • Recommended operating pressure: 20–50 psi (maximum 75 psi); flow range .06–4.75 GPM.
  • Ribbed-edge design for non-slip grip and easy installation; includes built-in filter to reduce clogging.
  • Durable brown cap, female-threaded compatibility, backed by a 5-year warranty.

Install the IPN-12H in I-PRO spray heads or any compatible spray body; verify proper radius by the color-coded cap. For best results, match pressure and spacing to local site conditions, and perform routine filter maintenance to prevent clogging and preserve uniform distribution.
