Yellow 4.37mm nozzle insert for Senninger Xcel-Wobbler sprinklers. The opening size sets the water flow at a given pressure; the sprinkler’s 18° white-top or 24° black-top head determines the spray trajectory and resulting coverage. Use this insert to replace a matching nozzle or change the sprinkler’s flow.
At 138 kPa this nozzle uses 865L/h. With an 18° white-top head it produces a 13.1m wetted diameter; with a 24° black-top head it produces a 15.7m wetted diameter. Both figures are measured at a 0.46m riser height.
| Pressure (kPa) | Flow (L/h) | 18° White-Top Diameter (m) | 24° Black-Top Diameter (m) |
|---|---|---|---|
| 69 | 611 | 11 | 13.6 |
| 103 | 749 | 12.7 | 15.4 |
| 138 | 865 | 13.1 | 15.7 |
| 172 | 968 | 13.4 | 16.5 |
Coverage figures are wetted diameters measured at a 0.46m riser height. Actual coverage depends on nozzle size, pressure, mounting height and field conditions. Wetted diameter is not sprinkler spacing.
Select the nozzle using the water available to the zone and the required sprinkler overlap. A larger opening increases flow at the same pressure; it also affects coverage. Use the performance chart rather than choosing by colour alone.
This is the nozzle insert only. The sprinkler head and its deflector remain separate components.
Warranty: 2 years.
