Replacement high-flow nozzle set engineered for Hunter PGP Ultra and I-20 rotors. This green nozzle rack includes four interchangeable nozzles that give you both high-flow and low-angle trajectory options to adapt sprinkler output for larger turf areas and different installation conditions.

  • Complete set: Includes four green nozzles in a convenient rack—two standard high-flow sizes (#10 and #13) and two low-angle high-flow sizes (#6 and #8).
  • Compatibility: Designed for use with Hunter PGP Ultra and I-20 rotor series; installs in the standard nozzle rack for these models.
  • Performance: Provides increased flow options for larger coverage and higher precipitation rates; refer to the Hunter performance chart for exact radius and GPM at differing pressures.
  • Easy service: Quick, drop-in replacement for worn or clogged nozzles; color-coded green for immediate identification of high-flow options.
  • Durability: OEM-grade materials for consistent spray pattern and long service life in residential and commercial irrigation systems.

Installation is straightforward—remove the rotor cover, replace the existing nozzles with the desired size from the rack, and verify pattern and radius at working pressure. For precise flow and radius numbers at specific pressures, consult the Hunter I-20/PGP Ultra High Flow Nozzle performance chart included in the product documents.

This set is an ideal solution when you need higher flow nozzles for larger turf zones or when adapting coverage without changing rotor bodies. Keep a spare rack on hand for quick on-site adjustments and routine maintenance.

Frequently Asked Questions

What rotors are these nozzles compatible with?
Compatible with Hunter PGP Ultra and I-20 rotor series; designed to drop into the standard nozzle rack.
How do I choose the right nozzle size?
Select low-angle (#6, #8) for tight or low-trajectory placements and standard high-flow (#10, #13) for larger coverage; verify with the performance chart.
Will these increase water output for larger zones?
Yes. These high-flow sizes provide higher GPM and precipitation rates—check the Hunter performance chart for exact flows at your operating pressure.
Where can I find installation or performance documentation?
A Hunter performance chart and spec sheet are included in the product documents; consult them for radius and flow at specific pressures.
