HUNTER PGJ-04 Rotor Sprinkler – 100 mm Pop-Up | Adjustable Arc | ½” BSP

The HUNTER PGJ-04 Rotor Sprinkler is a compact yet powerful gear-driven sprinkler designed for small to mid-sized turf areas. Featuring a 100 mm (4”) pop-up, adjustable arc (40° to 360°), and a ½” BSP female inlet, the PGJ-04 offers precision watering with the reliability of rotor technology in a scaled-down format.
