Rain Bird Rotary Nozzles 5-Pack R-VAN1318 13–18 ft Adjustable Radius for 1800 Series – Low-Drift, Low-Precipitation

Rain Bird R-VAN1318 is a 5-pack of adjustable rotary nozzles designed to upgrade 1800 Series spray heads for more uniform watering across 13–18 ft radii.

These Rain Bird rotary nozzles replace standard fixed-spray inserts to deliver rotating, low-angle streams that reduce runoff and improve distribution. Each set contains five RVAN18 nozzles engineered for compatibility with 1800 Series spray bodies, letting you convert pop-up sprays into efficient rotary emitters in minutes without changing risers or housings.

How do these nozzles change water distribution?

Rotary nozzles break a single broad spray into multiple rotating streams, which penetrates soil more slowly and evenly. That action helps water soak in rather than run off sloped or compacted surfaces.

• 13–18 ft adjustable radius covers medium lawn areas with fewer heads
• Rotating streams reduce misting and wind drift compared to fixed sprays
• Low precipitation rate helps prevent pooling on hard surfaces

Will these fit my existing 1800 Series spray heads?

Yes — the RVAN1318 nozzles are made specifically for Rain Bird 1800 Series bodies and replace original inserts without tools in most cases. They thread into the same seat and seat height as the factory nozzle, preserving pop-up and seal performance.

• Direct drop-in compatibility with 1800 Series spray head bodies
• No need to swap risers or housings for installation
• Works with standard 1800 Series gaskets and filters

How do I adjust the spray arc and radius?

Adjustment is straightforward: a simple dial or screw on the nozzle head changes arc and distance within the 13–18 ft range. You can set partial arcs for corner or edge heads and fine-tune distance to avoid overspray on sidewalks and driveways.

• Arc settings allow full, part-circle, and sector coverage
• Radius adjustable from 13 to 18 feet for flexible layout tuning
• Tool-free adjustments on most installation angles for quick tuning

What maintenance can I expect?

Rotary nozzles are low-maintenance but benefit from occasional inspection to remove debris and ensure smooth rotation. Seasonal checks and quick rinses will keep spray patterns consistent and prolong nozzle life.

• Rinse filters if water contains sediment
• Inspect rotation and clean quickly with a soft brush if needed
• Replace as a set to maintain matching coverage and uniform precipitation

Who is this for: Landscapers, property managers, and homeowners with Rain Bird 1800 Series spray systems who want improved uniformity, lower runoff, and flexible coverage without replacing bodies or risers. This 5-pack makes it easy to convert multiple heads at once for a consistent upgrade across medium-sized lawns, flower beds, and public green spaces.
