The connection set is an expansion set for the efficient Kärcher Rain System®, consisting of 4 T-connectors, 4 I-connectors, and 5 end pieces. The T-connector connects three Kärcher Rain System® and/or drip hoses, while the I-connector connects two. The water flow and thus the pressure can be adjusted at the side branch of the T-connector. For example, a drip hose can be connected here. The I-connector is ideal for attaching a drip hose at the end of a Kärcher Rain System® hose or for connecting two Kärcher Rain System® hoses. The end piece can be used to seal laid or shortened hoses. The hoses are easily installed without tools. You only need to slide the hose onto the connector or end piece and secure it with the union nut. The Kärcher Rain System® can be individually adapted to almost any garden and works perfectly with the SensoTimer to provide each plant with the right amount of water at the right time.
