Rainbird National Sls 18AP-C1 Adjustable Spray Nozzle

Product Description

The RAINBIRD NATIONAL SLS 18AP-C1 is an adjustable spray nozzle designed for residential and commercial irrigation systems. It covers a throw radius of 10.5 to 18 feet and features an infinite arc adjustment from 0 to 360 degrees, allowing precise coverage patterns for virtually any zone layout. The 18AP-C1 is engineered with a matched precipitation rate, which keeps water application consistent across the entire spray arc. Licensed irrigation contractors and landscape professionals install this nozzle as part of a spray head assembly in pop-up or fixed riser configurations.

This nozzle is suited for use in mixed-pattern irrigation zones where different spray patterns operate on the same valve circuit. The matched precipitation rate feature is critical in these setups because it ensures uniform water delivery regardless of arc setting, eliminating dry spots or overwatering that occur when unmatched nozzles are mixed. Typical applications include turf areas, groundcover beds, and landscaped zones in both residential and light commercial properties. Each package contains 25 nozzles, making this a practical choice for multi-head zone installations.

Installation Notes

Installation is typically performed by a licensed irrigation contractor or landscape irrigation technician. Shut off the irrigation system water supply and depressurize the line before removing or installing any nozzle. Thread the nozzle securely onto the spray head body and adjust the arc and radius settings before restoring system pressure. Verify matched precipitation rate compatibility with adjacent nozzles in the same zone to ensure uniform coverage.
