Rainbird National Sls 1804AP8 Adjustable Arc Spray Head

Product Description

The RAINBIRD NATIONAL SLS 1804AP8 is a professional-series adjustable arc spray head designed for residential and commercial irrigation systems. It delivers a fully adjustable spray pattern from 0 to 360 degrees with a spray distance of up to 8 feet, making it a versatile choice for turf and landscape zones of varying shapes. The 1804AP8 features a 4-inch pop-up height and a 1/2-inch inlet. Key construction elements include a patented pressure-activated co-molded wiper seal, a stainless steel retractable spring, and a stainless steel reduction screw. Licensed irrigation contractors and landscape technicians install this head as part of low-volume spray zones.

The 1804AP8 is suited for residential lawn irrigation, commercial landscape projects, and any application requiring flexible arc coverage in a compact pop-up body. The adjustable arc pattern allows a single head model to cover partial or full-circle zones without stocking multiple fixed-arc units. The removable grit filter helps protect the nozzle seat from debris common in field irrigation systems. Easy nozzle alignment simplifies installation and routine service in tight spacing layouts.

Installation Notes

Installation is performed by licensed irrigation contractors or qualified landscape technicians. Shut off system water supply and depressurize the lateral line before threading the head onto the riser or swing joint. Hand-tighten the 1/2-inch inlet connection to avoid cracking the body, then confirm final position before torquing with a strap wrench if needed. Verify local irrigation codes and backflow prevention requirements before placing the system into service.
