The Rain Bird R-VAN18-360 is a high-efficiency, fixed full-circle rotary nozzle engineered for residential and commercial lawn irrigation zones where complete 360° coverage is required. With a spacing range of 13 to 18 feet and a fixed 360° arc, this nozzle is purpose-built for circular turf areas — center-of-lawn installations, traffic islands, round planting beds, or any zone where every direction needs equal water distribution. It fits directly onto standard Rain Bird 1804, 1806, and 1812 spray bodies, 1/2" risers, and adapters, making it an ideal upgrade or replacement nozzle for existing spray head systems.
What makes the R-VAN18-360 stand out is its rotating stream technology, which distributes water through multiple slow-moving streams rather than a single fixed spray. This dramatically slows the application rate, giving water time to soak into the soil before runoff occurs. Compared to standard fixed spray nozzles, switching to R-VAN rotary nozzles can reduce flow by up to 60% and improve overall water efficiency by up to 30%. The nozzle maintains matched precipitation rates across the entire R-VAN product line — meaning R-VAN14, R-VAN18, and R-VAN24 nozzles can all run on the same zone without over- or under-watering. A built-in pull-up flush feature allows the nozzle to be manually purged of dirt and debris in the field without disassembly.
The R-VAN18-360 operates within a pressure range of 30 to 55 PSI (recommended 45 PSI), producing thick, wind-resistant water streams that resist misting and fogging — critical for water conservation in exposed or coastal environments. Radius can be reduced from 18 feet down by adjusting while the system is running. If you need a part-circle version at the same radius, consider the R-VAN18 adjustable arc nozzle (45° to 270°), or step up to the R-VAN24-360 for larger zones requiring 17 to 24 feet of coverage. DripWorks also carries a full range of compatible Rain Bird spray bodies and irrigation timers and controllers to complete your system.

What is the difference between the R-VAN18-360 and the R-VAN18 (adjustable arc)?
The R-VAN18-360 is a fixed full-circle nozzle — it always delivers a complete 360° spray pattern with no arc adjustment. The R-VAN18 adjustable arc version allows you to set the pattern anywhere from 45° to 270°, making it better suited for corners, edges, or irregularly shaped zones. Use the -360 version when you need complete circular coverage from a single head.
Which spray bodies is this nozzle compatible with?
The R-VAN18-360 is compatible with Rain Bird 1804, 1806, and 1812 spray bodies as well as standard 1/2" risers and adapters. It is NOT compatible with the older Rain Bird 1802 or 1803 spray bodies. If you're unsure what spray body you have, check the body cap for model markings. DripWorks carries a full selection of compatible Rain Bird spray bodies.
How does the R-VAN18-360 save water compared to a standard spray nozzle?
Standard fixed spray nozzles apply water very quickly in a single sheet, which often exceeds the soil's absorption rate and leads to runoff. The R-VAN's rotating multi-stream design applies water at a much slower rate — more like a gentle rain — giving the soil time to absorb each pass. Switching to R-VAN nozzles can reduce flow by up to 60% and improve water use efficiency by up to 30% compared to standard sprays.
What is the pull-up flush feature?
The pull-up flush feature lets you manually pull the nozzle upward to clear debris, dirt, or grass clippings from inside the nozzle without disassembling it or even removing it from the spray body. This is particularly useful in dusty or sandy soil conditions and helps maintain long-term performance without extra maintenance tools.
Can I mix R-VAN18-360 nozzles with other R-VAN models on the same zone?
Yes. All R-VAN nozzles are engineered with matched precipitation rates across the R-VAN14, R-VAN18, and R-VAN24 series, as well as across arc and pattern types. This means you can mix nozzles with different radii on a single zone and still achieve uniform water distribution — a major advantage over traditional spray nozzles.
How do I adjust the radius on the R-VAN18-360?
Radius adjustment must be made while the system is running. Use a small flat screwdriver or the Rain Bird adjustment tool to turn the radius adjustment screw on top of the nozzle. Turning it clockwise reduces the throw radius; counterclockwise increases it back toward the maximum 18 feet.
What operating pressure does this nozzle require?
The R-VAN18-360 operates between 30 and 55 PSI with optimal performance at the recommended 45 PSI. If your supply pressure exceeds 55 PSI, we recommend installing a pressure regulator upstream to protect the nozzle and ensure uniform performance. Operating above 55 PSI may cause misting, fogging, and uneven distribution.
Is the R-VAN18-360 eligible for water conservation rebates?
Possibly. Rain Bird R-VAN rotary nozzles are recognized as high-efficiency products and may qualify for water district rebate programs in many regions — particularly in water-conscious states like California, Arizona, Texas, Nevada, and Colorado. Check with your local water utility for current rebate eligibility.
