Impulssisadetin Gardena 8138-20 impulssisadetin harmaa oranssi

The Gardena 8138-20 Pulse Water Sprinkler with folding tripod is a stable solution for irrigating taller plants and medium to large garden areas. When set up, the tripod reaches approximately 100 cm in height. The sprinkler head is mounted on a G 1/2 (21 mm) thread and combines metal and plastic components for increased robustness. Adjustable rings show the selected sector and allow fine control of the spray from 25° to 360°. A high-precision brass nozzle ensures even water distribution, and a large rotary knob adjusts the range.

Advantages

The metal‑and‑plastic sprinkler head provides durability while keeping weight manageable. Visible adjustment rings enable quick and accurate sector setting. The brass nozzle improves distribution precision, and the rotary range control lets you set distances from 5 m up to 12.5 m. The folding tripod offers stable support at an operational height of about 100 cm.
