Made of brass, rust resistance, good thermal conductivity and heat resistance, can ensure long time using.. Nozzles produce a wide angle (170 degree), flat fan pattern that is great for broadcast spraying. The pre-orifice design of the Nozzles provide larger droplets that result in less drift, while providing a more precise flow and distribution pattern. Large, round orifice reduces clogging.
