The coupling with regulating valve provides more flexibility in watering the garden. With a single movement of the hand it is possible to regulate the flow of water and completely shut off. When the water is stopped, the connection device can be changed on the spot without having to turn off the water at the tap. The connection of a sprinkler to the practical adapter is also ideal, as this also allows the water flow and thus the range of irrigation to be adjusted with the help of the valve. Another feature is the UV and frost resistance, which allows year-round use. The durable quality product is Made in Europe and is supported by GARDENA with a warranty of five years after online registration.
