Rain Bird U-10Q dual-orifice spray nozzle - 90° quarter-circle - 2.1 to 3.1 m radius

Rain Bird U-10Q dual-orifice spray nozzle for lawn corners

The Rain Bird U-10Q is a high-efficiency dual-orifice spray nozzle with a fixed 90° quarter-circle spray pattern and a radius of 2.1 to 3.1 m. It is particularly suitable for automatic lawn irrigation in garden corners, along patios and within landscaped areas bordered by two straight edges. Its quarter-circle spray pattern directs water toward the intended lawn area without unnecessarily watering in every direction.

As part of the Rain Bird U-Series, the U-10Q features two separate spray openings designed to improve water distribution. One opening covers the outer watering area, while the second delivers water close to the sprinkler head.

Accurate quarter-circle coverage with a 3.1 m radius

The fixed 90° spray pattern makes the Rain Bird U-10Q an excellent choice for sprinklers installed in corners. It helps direct irrigation water onto lawn areas bordered by paths, patios, walls or garden beds.

The spray radius depends on the operating pressure. At 1.0 bar, the nozzle reaches approximately 2.1 m, increasing to 3.1 m at the recommended pressure of 2.1 bar. Its 12° spray trajectory produces a relatively low spray pattern. An integrated stainless steel adjustment screw allows the radius to be reduced when necessary.

Dual-orifice technology for improved close-in coverage

A distinctive feature of the Rain Bird U-10Q is its additional spray opening for close-in watering. While the main opening distributes water toward the outer edge of the spray pattern, the secondary opening delivers water immediately around the sprinkler body.

This design helps reduce dry patches near the sprinkler head and supports more uniform irrigation throughout the quarter-circle area. According to Rain Bird, U-Series nozzles can reduce water use by up to 30% compared with conventional spray nozzles when installed in properly designed irrigation systems. Actual savings depend on water pressure, sprinkler spacing and system operation.

Easy installation on Rain Bird spray bodies

The Rain Bird U-10Q is designed for use with compatible Rain Bird spray bodies and shrub adapters, including pop-up sprinklers from the Rain Bird 1800 Series. A fine mesh screen helps protect the lower spray opening from debris.

For installations with high supply pressure, pressure-regulated spray bodies help maintain consistent nozzle performance near the recommended operating pressure of 2.1 bar. The U-10Q can also be combined with suitable U-10H half-circle and U-10F full-circle nozzles to cover different sections of a lawn.

When planning your irrigation system, provide sufficient overlap between adjacent spray patterns and consider the flow requirements of every nozzle within the same watering zone.

Frequently asked questions about the Rain Bird U-10Q

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

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

Can the 90° spray angle be adjusted?

No. The U-10Q has a fixed quarter-circle spray pattern. Half-circle and full-circle versions are available separately in the U10 Series.

How much water does the U-10Q use?

The flow rate ranges from approximately 1.1 to 1.6 l/min, equivalent to around 66 to 96 litres per hour, depending on pressure.

Why does the nozzle have two spray openings?

The additional opening distributes water close to the sprinkler head, helping reduce dry patches and improve uniform coverage across the watering area.

Which sprinkler bodies are compatible?

The Rain Bird U-10Q fits compatible Rain Bird spray bodies and shrub adapters, including models from the Rain Bird 1800 Series.

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

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