Brand: Hunter Industries SKU: I25-06
Product Overview
The Hunter I25-06 is a 6-inch pop-up commercial gear-drive rotor with a plastic riser, adjustable 50- to 360-degree arc, standard drain check valve, and 1-inch female NPT inlet. The taller pop-up provides additional stream clearance over higher-cut turf and nearby plant material while retaining the flow capacity and long-range coverage of the I-25 platform.
Hunter’s current I-25 design combines adjustable part-circle and non-reversing full-circle operation in one rotor. Depending on the installed nozzle and operating pressure, the I25-06 provides an approximate radius range of 37 to 71 feet and flow from 3.8 to 31.5 GPM. Recommended and operating pressure is 40 to 100 PSI, with a standard nozzle trajectory of 25 degrees. Color-coded nozzles allow the system designer to match the rotor output to the site spacing, zone capacity, and available pressure.
Automatic arc return helps move the turret back to the programmed watering pattern if it is forced out of position, and the non-strippable drive mechanism helps protect the internal gears. QuickCheck supports through-the-top arc adjustment. The included check valve is designed to hold back up to 10 feet of elevation to reduce low-head drainage when the irrigation zone shuts off. Nozzle-package contents may vary, so confirm whether a specific nozzle is included before ordering.

Compatibility and Installation Notes
- Select the nozzle according to required radius, flow, spacing, and available pressure.
- Use a compatible 1-inch swing joint or threaded connection.
- Install the rotor level with finished grade and provide clearance for the full 6-inch pop-up.
- Confirm the irrigation zone can supply the selected nozzle flow at the required pressure.
- Use Hunter adjustment procedures for arc setup and nozzle installation.
- Confirm nozzle-package contents if a specific nozzle is required.
Frequently Asked Questions
Why choose the 6-inch I-25 instead of the 4-inch model?
The 6-inch pop-up provides additional clearance over taller turf or surrounding plant material.
Can the I25-06 operate full circle?
Yes. The rotor adjusts from 50 degrees through a non-reversing 360-degree full-circle pattern.
Does it include a check valve?
Yes. The standard check valve is designed to help prevent low-head drainage for elevation differences up to 10 feet.
