Gardena 3 Way Y Coupling.
The Gardena 3-way coupling divides your water source in two for connecting 3 x 13mm (1/2") hoses
With the use of Gardena 3-way Y-Coupling, hoses can be conveniently branched.
This allows simultaneous work in the garden, e.g. the lawn can be sprinkled while the hose is used for watering flower beds.
