Brand: Hunter Industries SKU: I-20-06-SS
Product Overview
The Hunter I-20-06-SS is a 6-inch pop-up gear-drive rotor with a stainless-steel riser, adjustable 50- to 360-degree arc, standard drain check valve, and 3/4-inch female NPT inlet. The taller riser provides additional clearance over higher-cut turf and groundcover while the stainless sleeve adds durability for residential, commercial, and high-traffic irrigation applications.
The rotor uses Hunter I-20 nozzle options to match the required radius, flow, and trajectory. Across the available nozzle range, Hunter publishes approximately 17 to 46 feet of radius and 0.36 to 14.8 GPM. Recommended pressure is 25 to 70 PSI, with an operating range of 20 to 100 PSI. Standard nozzles have a 25-degree trajectory, and compatible low-angle nozzles have a 13-degree trajectory.
FloStop control allows flow through the individual rotor to be stopped while the remainder of the zone continues operating, supporting nozzle changes and service. Automatic arc return helps move the turret back to the programmed watering pattern after it is forced out of position, and the non-strippable drive mechanism protects the internal gears. The included check valve is designed to reduce low-head drainage for elevation differences up to 10 feet.

Compatibility and Installation Notes
- Select a compatible Hunter I-20 nozzle based on design flow, radius, trajectory, and available pressure.
- Connect to a compatible 3/4-inch swing joint or threaded fitting.
- Install level with finished grade and provide clearance for the 6-inch riser.
- Use Hunter adjustment procedures for arc and radius setup.
- Confirm nozzle-package contents if a specific nozzle is required.
Frequently Asked Questions
Why use the 6-inch model instead of the 4-inch I-20?
The taller pop-up provides additional stream clearance over higher turf or nearby plant material.
Is the stainless riser the same as a stainless body?
No. The rotor uses a stainless-steel riser sleeve while the surrounding rotor body remains the designed irrigation housing.
