Question about Gardena Spiral hose set

Yes, it is possible to connect two spiral hoses together. You should use the appropriate Gardena connecting elements for the connection, some of which are included in the scope of delivery or are available separately. The Gardena multi-coupling with 12.7 mm (1/2 inch) does not fit as the spiral hose has a diameter of 9 mm and therefore a smaller coupling is required. Therefore, use the Gardena couplings specially designed for 9 mm hoses.
