The GARDENA Ribbed Pond Hose is a connecting hose for 13 mm (1/2") connections that can be used in and out of the pond. With a diameter of 13 mm, this Ribbed Pond Hose is specially suited for the connection of pond figures and source stones. The hose is black and made of opaque PE material. Through the special ribbed design, it is especially flexible and retains its shape. Flat connecting points allow water-tight connections. The material of the hose is free of cadmium, lead and barium, and free of recycled impurities – and thereby plant- and animal-friendly.
