Rainbird National Sls 15-H-C1 Half Circle Sprinkler Nozzle

Product Description

The RAINBIRD NATIONAL SLS 15-H-C1 is a half-circle pattern replacement nozzle designed for underground pop-up sprinkler heads in residential and commercial irrigation systems. It features a matched precipitation rate, which keeps water application consistent even when half-circle, quarter-circle, and full-circle nozzles are mixed within the same irrigation zone. This prevents over- or under-watering at pattern overlap points. Licensed irrigators and landscape contractors install this nozzle as a direct replacement when worn or damaged nozzles cause uneven distribution. Each package contains 25 nozzles, making it practical for multi-head zone retrofits or service truck stock.

This nozzle fits most standard underground pop-up sprinkler bodies and is intended for use in turf and landscape irrigation zones where half-circle coverage is required. The matched precipitation rate feature is especially important in mixed-pattern zones, where running different arc nozzles from the same valve is a standard design practice. It is suited for both new installations and replacement service work on existing irrigation systems.

Key Features

• Half-circle arc pattern provides 180-degree coverage for edges, borders, and rectangular turf areas
• Matched precipitation rate ensures uniform water application when mixed with other arc pattern nozzles on the same zone
• Fits most underground pop-up sprinkler heads for broad replacement compatibility
• Sold in a 25-unit package, suitable for multi-head zone service or contractor restocking
• Direct replacement design allows nozzle swap without replacing the full sprinkler body

Compatibility

Designed as a replacement nozzle for most underground pop-up sprinkler heads. Consult the sprinkler body manufacturer specifications to confirm nozzle thread and seat compatibility before installation.

Installation Notes

Nozzle replacement on pop-up sprinklers is typically performed by licensed irrigators or landscape maintenance technicians. Shut off the irrigation zone valve and relieve system pressure before removing the existing nozzle. Hand-tighten the replacement nozzle to avoid cross-threading or cracking the nozzle seat. After installation, cycle the zone and verify arc pattern alignment and precipitation uniformity across all heads in the zone.
