The Hunter PGJ 6" Rotor was engineered to deliver all the efficiency advantages of a full-size rotor in a compact, spray-sized package — making it the go-to upgrade for residential lawns, ground cover plantings, low-pressure zones, and any application where a traditional spray head has historically been used. With an adjustable arc from 40° to 360°, a throw radius of 15 to 34 feet, and a ½" NPT female inlet, the PGJ bridges the gap between fixed spray heads and large-format rotors beautifully.
What makes the PGJ especially versatile is its ability to work in tandem with larger rotors — like the Hunter PGP Ultra — on the same valve zone. Because both rotors are designed with matched precipitation rates in mind, you can cover irregularly shaped areas with a mix of head sizes without creating over- or under-watered patches. The PGJ ships with a factory-installed 2.0 nozzle and a full nozzle tree (8 nozzles, ranging from 0.75 to 5.0) so you can dial in the exact radius and flow rate your zone demands right out of the box.
Key design features include Hunter's QuickCheck™ Arc Mechanism for rapid field arc verification, through-the-top arc adjustment using a standard flat-blade screwdriver or Hunter wrench, and a factory-installed rubber cover for long-term durability and UV protection. The water-lubricated gear drive keeps the mechanism running smoothly throughout its service life without the need for greasing or external lubrication. If your system has elevation changes, Hunter also offers a check valve version of the PGJ that prevents low-head drainage on sloped sites — browse our full rotor selection or contact DripWorks for availability.
Looking to automate your PGJ zone with a smart controller, or need valves to control each circuit independently? DripWorks carries a complete line of compatible irrigation timers and controllers and solenoid valves to complete your system.

What is the Hunter PGJ designed to replace?
The PGJ was purpose-built to replace fixed spray heads in applications where a traditional spray nozzle is commonly used. Where a spray head would require 9 heads to water a 28' square lawn, 4 PGJ rotors can do the same job — using less water per minute, with a lower precipitation rate that reduces runoff and pooling on compacted soils.
Can the PGJ be mixed on the same valve zone as larger rotors like the PGP Ultra?
Yes — this is one of the PGJ's best features. Hunter designed the PGJ with precipitation rates that are compatible with its larger rotors, so you can place PGJ heads in tighter areas alongside PGP Ultra rotors covering wider sections — all on the same valve — without creating wet or dry spots from mismatched application rates.
What is the QuickCheck™ Arc Mechanism?
The QuickCheck™ Arc Mechanism allows you to visually confirm the arc setting at a glance while standing over the head in the field — without needing to run the system. This significantly speeds up installation and maintenance checks, especially when adjusting multiple heads on a large property.
What does "through-the-top arc adjustment" mean?
Arc adjustment on the PGJ is performed from the top of the sprinkler body using a flat-blade screwdriver or a Hunter rotor adjustment tool. You do not need to dig out the head or remove it from the ground to change the arc — a significant time-saver compared to older designs that required body removal.
How do I change nozzles on the PGJ?
The PGJ ships with a nozzle tree of 8 nozzles and the 2.0 nozzle pre-installed at the factory. To swap nozzles, simply pull up the pop-up riser, pull the nozzle out of the nozzle seat, and snap in the desired replacement. No tools are required for nozzle changes. Hunter also offers video guides on nozzle installation linked in the Downloads section below.
What is the minimum pressure required?
The PGJ can operate at pressures as low as 20 PSI, though the recommended range for optimal coverage and uniformity is 30 to 50 PSI. At low pressures, radius and rotation consistency may be reduced. If your system pressure exceeds 70 PSI, a pressure regulator is recommended to protect the nozzles and ensure even precipitation.
Is there a version with a check valve?
Yes. Hunter offers a check valve version of the PGJ that holds water in the lateral line after the system shuts off — preventing low-head drainage on sloped sites. If your system has grade changes of more than a foot or two, the check valve version is highly recommended. Contact DripWorks to ask about availability, or browse our full rotor selection.
What is the difference between the PGJ and the PGP Ultra?
The PGJ is a lighter-duty, compact rotor with a ½" inlet, suited for small-to-mid residential zones with a radius of 15–34 feet and flows up to 4.3 GPM. The PGP Ultra is Hunter's heavy-duty premium rotor with a ¾" inlet, covering up to 46 feet and handling up to 14.8 GPM — ideal for large residential lawns, commercial landscapes, and sports fields. For medium-sized areas where a spray head would feel underpowered, the PGJ is often the ideal fit.
