Rainbird National Sls 1802AP4 Adjustable Arc Spray Head

Product Description

The RAINBIRD NATIONAL SLS 1802AP4 is a professional-series pop-up arc spray head designed for residential and commercial irrigation systems. The head features a 2-inch pop-up height and delivers an adjustable spray pattern from 0 to 360 degrees, covering a spray distance of up to 4 feet. A patented pressure-activated co-molded wiper seal keeps debris out of the stem during retraction. Stainless steel components — including the reduction screw and retractable spring — provide corrosion resistance in wet, soil-contact environments. A removable grit filter protects internal passages from sediment. Landscape irrigation technicians and irrigation contractors are the primary installers of this head.

The 1802AP4 is suited for turf and groundcover zones in both residential and light commercial landscapes. The adjustable arc nozzle makes it practical for irregularly shaped zones where fixed-arc heads would cause overspray onto pavement or structures. The easy nozzle alignment feature allows on-site arc adjustment without specialty tools. The 0.5-inch inlet threads into standard swing-joint assemblies or pop-up risers used throughout typical low-voltage drip and spray irrigation systems.

Compatibility

Designed as an OEM-style replacement or new-installation spray head for professional-grade pop-up irrigation systems using a 0.5-inch inlet connection.

Installation Notes

Installation is typically performed by licensed irrigation contractors or landscape irrigation technicians. Shut off the irrigation zone valve and relieve system pressure before removing or installing any spray head. Thread the 0.5-inch inlet carefully into the swing joint or riser fitting to avoid cross-threading — hand-tighten first, then snug with an appropriate wrench. Verify arc adjustment and spray distance after restoring pressure before finalizing grade and sod replacement around the head.
