The male inlet threads are compatible with Toro spray heads. 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.
