Rain Bird U-10F dual-orifice spray nozzle - 360° full-circle - 2.1 to 3.1 m radius

Rain Bird U-10F dual-orifice full-circle spray nozzle

The Rain Bird U-10F is a high-efficiency dual-orifice spray nozzle with a fixed 360° full-circle spray pattern and a radius of 2.1 to 3.1 m. It is designed for automatic irrigation of central lawn areas and landscaped spaces where water needs to be distributed in every direction around the sprinkler.

As part of the Rain Bird U-Series, the U-10F features two separate spray openings that work together to improve watering uniformity. The main opening distributes water toward the outer edge of the spray pattern, while the additional opening provides close-in coverage around the sprinkler head.

Complete 360° coverage for central lawn areas

With its fixed full-circle spray pattern, the Rain Bird U-10F waters the entire area surrounding the sprinkler. This makes it particularly suitable for pop-up sprinklers installed within a lawn rather than along its edges. Unlike quarter-circle and half-circle nozzles, the U-10F distributes water in every direction without requiring arc adjustment.

The spray radius varies from 2.1 to 3.1 m depending on operating pressure. At the recommended pressure of 2.1 bar, the nozzle achieves a radius of approximately 3.1 m. Its 12° trajectory produces a relatively low spray pattern. An integrated stainless steel adjustment screw allows the radius to be reduced to suit the available space.

Dual-orifice technology for uniform water distribution

The Rain Bird U-10F uses two spray openings to deliver water across the entire circular watering area. While the upper opening provides coverage at greater distances, the lower opening directs water close to the sprinkler body. This helps reduce dry patches around the sprinkler head and improves watering uniformity.

More uniform coverage can also help improve irrigation efficiency. According to Rain Bird, U-Series nozzles can use up to 30% less water than conventional spray nozzles under suitable installation conditions. Actual savings depend on sprinkler spacing, operating pressure and watering schedules.

Easy installation and irrigation system planning

The Rain Bird U-10F is compatible with Rain Bird spray bodies and suitable shrub adapters, including pop-up sprinklers from the Rain Bird 1800 Series. A fine mesh filter screen helps protect the lower spray opening from debris. For installations with higher water pressure, Rain Bird recommends pressure-regulated spray bodies to maintain consistent nozzle performance.

The U-10F can be combined with suitable U-10Q quarter-circle and U-10H half-circle nozzles to cover different sections of a lawn. Because the full-circle version irrigates a larger area, it requires a higher flow rate than the other models. When designing your irrigation system, consider the total available water supply and allow sufficient overlap between adjacent spray patterns.

Frequently asked questions about the Rain Bird U-10F

What is the spray radius of the Rain Bird U-10F?

The spray radius ranges from 2.1 to 3.1 m depending on water pressure. At the recommended pressure of 2.1 bar, the nozzle reaches approximately 3.1 m.

Can the 360° spray angle be adjusted?

No. The U-10F has a fixed full-circle spray pattern. Quarter-circle and half-circle versions are available separately within the U10 Series.

How much water does the U-10F use?

The flow rate ranges from 4.4 to 6.2 l/min, equivalent to approximately 264 to 372 litres per hour, depending on operating pressure.

What is the advantage of the dual-orifice design?

The additional opening delivers water close to the sprinkler head, helping improve watering uniformity and reduce dry patches around the spray body.

Which sprinkler bodies are compatible?

The Rain Bird U-10F is compatible with Rain Bird spray bodies and suitable shrub adapters, including models from the Rain Bird 1800 Series.

Can the U-10F be combined with other U10 nozzles?

Yes. The U-10F can be combined with suitable U-10H half-circle and U-10Q quarter-circle nozzles. Their different flow rates must be considered when designing the irrigation zone.
