HUNTER MP820 360° FEMALE-THREADED ROTARY NOZZLE

Hunter MP820 full-circle rotary nozzle for open lawns and larger garden areas. Multiple rotating streams provide even coverage and help resist wind drift. The MP800 family applies water faster than Standard MP Rotators, making it useful where watering time is limited, while applying water more slowly than traditional spray nozzles. The double-pop design helps protect the nozzle from dirt and debris during startup. The top adjustment screw lets you shorten the watering distance. The full-circle pattern stays fixed. Sprinkler body sold separately.

✓ Coverage: 6.7 metre radius at 280 kPa pressure
✓ Spray Pattern: Fixed 360° full circle
✓ Flow: 14.99 L/min at 280 kPa pressure
✓ Recommended Pressure: 280 kPa
✓ Compatibility: Female nozzle thread suits Hunter Pro-Spray sprinkler bodies

Hunter MP820 full-circle rotary nozzle for open lawns and larger garden areas.

Multiple rotating streams provide even coverage and help resist wind drift. The MP800 family applies water at approximately 20 mm/hour, faster than Standard MP Rotators but more slowly than traditional spray nozzles. This is useful where watering time is limited and the water supply can support the required flow.

The double-pop design helps protect the nozzle from dirt and debris during startup. A removable filter screen allows cleaning when needed.

At the recommended 280 kPa pressure, the MP820 waters a 6.7 metre radius. Radius is the distance from the sprinkler to the outer edge of the spray. Flow is 14.99 L/min at this pressure. The top adjustment screw lets you shorten the watering distance while the 360° pattern stays fixed.

Keep MP800 nozzles on a separate irrigation zone from Standard MP Rotators. MP strip nozzles can match either family with the appropriate spacing and layout.

Female nozzle thread suits Hunter Pro-Spray sprinkler bodies. Sprinkler body sold separately. The nozzle can also be used with matching shrubhead adaptors where pop-up is not required, typically installed on top of a riser.

Warranty: Three years.

✓ Product Type and Application
Hunter MP-820-360 MP800-family rotary nozzle for lawn and landscape areas needing full-circle coverage.

✓ Coverage and Spray Pattern
Radius: 6.7 metres at 280 kPa pressure, before radius reduction.
Radius is the distance from the sprinkler to the outer edge of the watering pattern.
Radius range: 4.6–7.3 metres, depending on pressure and adjustment.
Spray pattern: Fixed 360° full circle.

✓ Radius Reduction
Use the Hunter MP Rotator Adjustment Tool (MPTOOL) or a small flathead screwdriver on the top adjustment screw. Turn clockwise to reduce radius and counterclockwise to increase it. Radius reduction is up to approximately 25%.
For minimum radius settings, regulate your system pressure to 210 kPa pressure and reduce the radius with the nozzle's radius adjustment.
A slip clutch limits reduction to maintain reliable rotation. The adjustment screw does not completely shut off the nozzle.
The full-circle arc stays fixed.

✓ Pressure & Flow
Recommended operating pressure: 280 kPa.
Maximum continuous nozzle pressure: 380 kPa.
Radius and flow at different pressures:
210 kPa: 6.1 metre radius; 12.85 L/min.
250 kPa: 6.4 metre radius; 13.92 L/min.
280 kPa: 6.7 metre radius; 14.99 L/min.
300 kPa: 6.7 metre radius; 15.41 L/min.
350 kPa: 7.0 metre radius; 16.27 L/min.
380 kPa: 7.3 metre radius; 17.13 L/min.

✓ Precipitation Rate
Precipitation rate describes how quickly water is applied across the area, measured in millimetres per hour.
MP800-family rate: Approximately 20 mm/hour.
At 280 kPa: 20 mm/hour with square spacing; 23 mm/hour with triangular spacing.
Keep MP800 on separate zones from Standard MP Rotators, which apply approximately 10 mm/hour. MP strip matching depends on spacing and layout.

✓ Automatic Matched Precipitation
Flow adjusts as the radius changes to help maintain the MP800-family precipitation rate.

✓ Connection and Compatibility
Female nozzle thread suits Hunter Pro-Spray sprinkler bodies. Sprinkler body sold separately. The nozzle can also be used with matching shrubhead adaptors where pop-up is not required, typically installed on top of a riser.

✓ Pressure Regulation
Hunter Pro-Spray PRS40 regulates pressure to 280 kPa for normal radius settings. PRS30 regulates pressure to 210 kPa for minimum radius settings, used with radius adjustment.

✓ Debris Protection and Filtration
Double-pop design keeps the nozzle protected until the sprinkler riser has fully extended. A removable filter screen helps prevent clogging and allows cleaning.

✓ Identification
Model: MP-820-360.
820 identifies the MP800-family model covering a 4.6–7.3 metre radius range. 360 identifies fixed full-circle coverage.
Colour: Red and grey.
Connection: Female nozzle thread.

✓ Warranty
Three years.
