Hunter PGP-ADJ 3/4" Rotor Sprinkler Head, Adjustable 40°-360° Arc, 4" Pop-Up Gear Drive Lawn Irrigation Head, 22-52 ft Spray Distance, Preinstalled 3.0 GPM Nozzle

The Hunter PGP-ADJ isn’t just a sprinkler head — it’s the original gear-driven rotor that professionals and homeowners trust for precise, long-lasting irrigation. Engineered for performance and built to withstand the elements, this rotor delivers even coverage and flexible control across a wide range of lawn and landscape applications. Featuring an adjustable arc from 40° to 360°, the PGP-ADJ is ideal for both full-circle and part-circle watering zones. A powerful spray radius of 22 to 52 feet allows for greater spacing and fewer heads per zone. With a flow range of 0.5 to 14.1 GPM and a precipitation rate of approximately 0.4 in/hr, it’s built to match diverse system needs without compromising efficiency. The ¾-inch NPT inlet connection and 4-inch pop-up height make installation simple and compatible with most existing systems. Operating pressure ranges from 20 to 100 PSI, with a recommended pressure range of 25 to 70 PSI for optimal performance. Nozzle trajectory options include a standard 25° angle and a low-angle 13° nozzle for wind resistance or slope applications. Whether you're replacing an old sprinkler head or building a new irrigation system, the PGP-ADJ delivers industry-leading reliability, smooth gear-driven rotation, and customizable watering with every use.
