The brass spray nozzle offers several advantages over a traditional plastic spray nozzle. First and foremost is the precision-machining that is possible with brass construction which means that the spray is extremely uniform. Second is the durability of brass, particularly its ability to stand up to lawn equipment like trimmers and edgers which can shear off plastic spray nozzles. Third is the unique twin spray of the half- and quarter-pattern brass nozzles which ensures extremely even coverage against sidewalks and driveways where “hot spots” tend to occur. The all-brass spray nozzle includes a filter and adjustment screw which allows you to reduce the spray pattern down to 75 percent of its rated distance. The female inlet threads are compatible with Orbit, Hydro-Rain, and other major brands. For optimum efficiency pair the brass spray nozzle with a professional series pressure-regulating pop-up spray body set at 30 PSI. For outdoor irrigation use with cold water only. Color: Metallics.
