The Professional Series Spray Head is the premium offering in the Orbit sprinkler assortment. This pop-up spray head features a highly innovative pressure regulator which can be adjusted from the bottom before installation, or from the top after installation, from 30 to 40 PSI. 30 PSI is recommended for spray nozzles while 40 PSI is recommended for multi-stream rotator nozzles. It is available in 2, 3, and 4 in. riser stem heights and is ideal for a broad range of landscape types. The wiper seal features an over-molded structural support that ensures long-term, smooth retraction to prevents water from blowing by the riser stem. The riser spring which creates the pop-up action is made of corrosion-resistant stainless steel for years of reliable operation. Includes a ratchet mechanism in the riser stem allowing for adjustment of the direction of the spray after installation. The spray body inlet has a standard 1/2 in. female pipe threads (FPT) which connects to both Blu-Lock and Riser-Flex fittings, 1/2 in. Schedule 80 PVC, and cut-off risers. The brass spray nozzle features precision-machining making the spray both uniform and durable. The half and quarter pattern nozzles feature twin-spray technology. 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. Its low-angle trajectory improves efficiency by minimizing wind drift. For outdoor irrigation use with cold water only. Color: Blacks. Material: Plastic.
