Rain Bird MPR-8Q spray nozzle - 90° quarter-circle - 1.7 to 2.4 m radius

Rain Bird MPR-8Q spray nozzle for lawn corners

The Rain Bird MPR-8Q is a fixed-pattern spray nozzle with a 90° quarter-circle spray pattern and a radius of 1.7 to 2.4 m. It is particularly suitable for automatic irrigation of small to medium-sized lawn corners, compact landscaped areas and gardens with clearly defined boundaries. Its quarter-circle spray pattern provides targeted watering where two straight lawn edges meet.

The MPR-8Q belongs to the Rain Bird MPR Series, which features matched precipitation rates for coordinated water distribution. It is designed for irrigation systems where different spray patterns need to work together. Choosing the correct nozzle helps provide reliable lawn irrigation while reducing unnecessary watering outside the intended grass area.

90° quarter-circle coverage with up to 2.4 m radius

The fixed 90° spray angle makes the Rain Bird MPR-8Q a practical choice for sprinklers installed in lawn corners. Typical applications include grass areas next to patios, garden paths, walls and flower beds. The nozzle distributes water over a quarter-circle area, helping keep irrigation focused on the lawn.

The spray radius ranges from 1.7 to 2.4 m depending on operating pressure. At the optimum pressure of 2.1 bar, the nozzle reaches approximately 2.4 m. Its 10° spray trajectory supports water distribution over this distance. An integrated stainless steel adjustment screw allows the radius to be reduced when required.

Matched precipitation rates for uniform irrigation

MPR stands for Matched Precipitation Rate. Rain Bird MPR nozzles are designed with coordinated precipitation rates across different spray patterns. This makes it easier to combine quarter-circle, half-circle and full-circle nozzles in a properly designed irrigation system while maintaining balanced water application.

The Rain Bird MPR-8Q has a flow rate of approximately 0.7 to 1.0 l/min depending on operating pressure. At 2.1 bar, this corresponds to about 60 litres per hour. Correct sprinkler spacing, adequate overlap and suitable operating pressure are essential for uniform irrigation across the entire lawn.

Easy installation and flexible irrigation planning

The Rain Bird MPR-8Q fits compatible Rain Bird spray bodies and suitable shrub adapters, including models from the Rain Bird 1800 Series. A blue fine-mesh filter screen helps protect the nozzle from debris. The stainless steel adjustment screw allows convenient radius adjustment during installation.

For a complete irrigation system, the MPR-8Q can be combined with suitable MPR-8H half-circle and MPR-8F full-circle nozzles. These models have comparable spray radii at the same operating pressure but different spray patterns and flow rates. Make sure adjacent sprinklers overlap sufficiently and the available water supply meets the requirements of the irrigation zone.

Frequently asked questions about the Rain Bird MPR-8Q

What is the spray radius of the Rain Bird MPR-8Q?

The spray radius ranges from 1.7 to 2.4 m depending on operating pressure. At 2.1 bar, the nozzle reaches approximately 2.4 m.

Can the 90° spray angle be adjusted?

No. The MPR-8Q has a fixed quarter-circle spray pattern. However, the radius can be reduced using the integrated stainless steel adjustment screw.

How much water does the MPR-8Q use?

The flow rate ranges from 0.7 to 1.0 l/min, equivalent to approximately 42 to 60 litres per hour.

What does MPR mean?

MPR stands for Matched Precipitation Rate. These nozzles are designed to provide coordinated precipitation rates across different spray patterns in a correctly planned irrigation system.

Which sprinkler bodies are compatible?

The Rain Bird MPR-8Q fits compatible Rain Bird spray bodies and shrub adapters, including models from the Rain Bird 1800 Series.

What is the difference between MPR-8Q and MPR-8Q-FLT?

The standard MPR-8Q has a 10° spray trajectory. The MPR-8Q-FLT is a flat-trajectory version with a 5° spray trajectory and different flow characteristics.
