Rainbird National Sls 1804AP4 Adjustable Arc Spray Head

Product Description

The RAINBIRD NATIONAL SLS 1804AP4 is a professional-series adjustable arc spray head designed for residential and commercial irrigation systems. It features a 4-inch pop-up height and an adjustable spray pattern ranging from 0 to 360 degrees, making it adaptable to a wide range of zone layouts. The spray distance reaches up to 4 feet. A patented pressure-activated co-molded wiper seal keeps the riser clean and extends service life. A stainless steel retractable spring ensures reliable retraction after each cycle. Licensed irrigation contractors and landscape professionals are the typical installers of this head.

The 1804AP4 is suited for turf and groundcover zones in both residential and light commercial irrigation applications. Its 1/2-inch inlet is compatible with standard lateral pipe connections used in low-volume spray zones. The adjustable arc makes it practical for irregular or corner areas where fixed-pattern heads would create overspray or dry spots. The removable grit filter helps protect the nozzle in systems with moderate sediment loads, reducing service calls. Easy nozzle alignment allows for quick field adjustment without specialty tools.

Installation Notes

Installation is performed by licensed irrigation contractors or qualified landscape professionals.

Hand-tighten the inlet connection to avoid cracking the body, then confirm arc adjustment and spray distance with the system running at normal operating pressure. Follow all applicable local irrigation and plumbing codes during installation.
