Hunter PGP-ADJ 3/4" Rotor Sprinkler Head, 4" Pop-Up — 22–52 ft Radius, 40–360° Adjustable

The Hunter PGP-ADJ is a durable gear-driven rotor sprinkler that delivers adjustable 40°–360° arcs and a 22 to 52-foot spray radius for dependable, professional-grade lawn irrigation.

Designed as the original gear-driven rotor trusted by landscape professionals and homeowners, the PGP-ADJ combines long throw, simple arc adjustment, and reliable operation. Built to resist clogging and operate quietly, this sprinkler head fits most systems with a 3/4" female NPT inlet and a 4" pop-up height. Its broad flow and pressure envelope makes it adaptable for retrofit projects and new installations alike.

How far and how flexibly can the PGP-ADJ water my yard?

The PGP-ADJ offers a wide spacing range so you can cover large areas with fewer heads. It ships with a 3.0 GPM nozzle and provides an adjustable radius of about 22 to 52 feet, while the arc can be set anywhere between 40° and 360° to accommodate part-circle or full-circle zones.

• Spray distance: approximately 22–52 ft
• Preinstalled nozzle: 3.0 GPM (nozzles sold separately for other outputs)
• Arc adjustment: 40° to 360° for custom coverage
• Precipitation rate: roughly 0.4 in/hr for the standard setup

What operating pressures and flows does this rotor handle?

This rotor performs across a broad range of pressures and flows, making it suitable for different pipe sizes and pump systems. It operates between 20 and 100 PSI, with a recommended range of 25–70 PSI, and accepts flows from 0.5 to 14.1 GPM depending on nozzle choice.

• Operating pressure range: 20–100 PSI
• Recommended operating pressure: 25–70 PSI
• Flow range: 0.5–14.1 GPM with various nozzles
• Nozzle trajectory options: standard 25° or low-angle 13° for wind or slope conditions

How reliable and low-maintenance is the PGP-ADJ over time?

Gear-driven and water-lubricated, the PGP-ADJ is engineered for quiet, consistent rotation and a long service life. Its internal drive resists clogging and requires minimal routine attention, while the compact pop-up body and standard inlet make replacement straightforward if needed.

• Water-lubricated gear drive for smooth, quiet rotation
• Resistant to common clogging issues in typical irrigation systems
• Standard 3/4" female NPT inlet for easy compatibility
• Retracted body height 7¾"; exposed spray diameter 1¾" for simple installation

Can I adapt this rotor for windy conditions or sloped lawns?

Yes—choose the low-angle nozzle option when wind or grade affects spray performance. The PGP-ADJ accepts different nozzle trajectories and outputs so you can reduce drift on exposed properties or improve distribution on inclines.

• Low-angle nozzle: 13° trajectory to reduce wind drift
• Standard nozzle: 25° for normal conditions
• Swap nozzles to fine-tune precipitation rate and radius
• Nozzles available separately for performance customization

Who is this for: The Hunter PGP-ADJ is aimed at homeowners upgrading older heads, landscape contractors specifying reliable rotors, and property managers who need a robust, adjustable sprinkler that covers large areas with fewer units. If you require long throw, proven durability, and flexible nozzle options to solve wind, slope, or spacing challenges, this rotor is a practical choice.
