The Rainbird 15H sprinkler nozzle 25pack fits on all of the brand's spray heads and shrub adapters. It features halfcircle spray sprinkling action and a filter screen that prevents clogging. A durable stainless steel adjustment screw makes it easy to change the sprinkler's flow and radius.Matched Precipitation Rate (MPR) nozzles simplify the design process by allowing sprinklers with various arcs and radii to be mixed on the same circuit. MPR spray head nozzles are now colorcoded on top to enhance your productivity. Top Colorcoding makes it easy to verify proper nozzle installation, even when system is not operating. Now it's easier to sort, easier to organize, and easier to install with Top Colorcoded nozzles, now distinctly Rainbird.Selecting the correct nozzle is one of the most crucial, yet overlooked, elements in irrigation system design. Choosing the correct nozzle, whether it's for a spray head or a rotor, is easy if you take the time to study the nozzle charts in a manufacturer's product or online catalog and select one that best suits your needs; irrigation equipment manufacturers have put a tremendous amount of effort into developing nozzles to fit almost every application: For slopes and compacted soils, select a nozzle with a lower precipitation rate. For windy areas, select a nozzle with a low nozzle outlet trajectory. To achieve even water distribution without having to separate partcircle from fullcircle sprinklers, select a nozzle set that features a matched precipitation rate. Another way to ensure uniform watering, if you're working with spray heads, is to select nozzles that have an undercut nozzle. These nozzles have an second, undercut orifice for watering closer to the head. For flexibility with spray heads, select a nozzle with an adjustable or variable arc. Because nozzles are designed to work within a wide range of pressures, it is important to ensure you have the correct pressure at the base of the nozzle.
