The GARDENA System Stop 'n' Spray Set includes a Water Stop (Art. No. 913-50) and a GARDENA Classic Adjustable Spray Nozzle (Art. No. 8114-50). Thanks to the Water Stop at the end of hose, water is stopped automatically at disconnection, at connection it flows again. This saves a trip to the tap e.g. when nozzles need to be changed. The Water Stop is suitable for 13 mm (1/2") hoses.
