The original system branching set includes a Y-piece and three hose connectors. With the help of the Y-piece, hoses can be easily branched. This way, you can water the lawn and spray with a second hose at the same time in the garden. The Y-piece can also be used to adapt from 19 mm (3/4") hoses to 13 mm (1/2") and 15 mm (5/8") hoses. The connection can be easily detached. With this set, you receive all the original system parts for a hose connection.
