The adjustable pattern spray nozzle is engineered to deliver uniform droplet sizes across a 0-to-360-degree arc. It includes a filter and adjustment screw which allows you to reduce the spray pattern down to 75 percent of its rated distance. Its low-angle trajectory helps improve efficiency by minimizing wind drift. The female inlet threads are compatible with Orbit, Hydro-Rain, and other major brands. The adjustable pattern nozzle is available in 4-, 8-, 10-, 12-, 15- and 18-ft. radius versions, each with a color-coded body for fast identification. For optimum efficiency pair the adjustable pattern spray nozzle with a professional series pressure-regulating spray body set at 30 PSI. For outdoor irrigation use with cold water only.
