The connection set is a supplementary kit for the efficient Kärcher Rain System irrigation system and includes 4 T-pieces, 4 I-pieces, and 5 end pieces. The T-piece connects three Kärcher Rain System or drip hoses, while the I-piece connects two. The side outlet of the T-piece is adjustable in quantity and thus pressure-regulating, making it ideal for connecting the drip hose. The I-piece is perfect for attaching the drip hose to the end of the Kärcher Rain System hose or for connecting two Kärcher Rain System hoses. With the help of the end piece, the laid or shortened hoses can be closed off at any point. The assembly of the hoses is tool-free and very easy: simply slide the hose onto the connection or end piece and secure it with the nut. The Kärcher Rain System can be individually adapted to almost any garden and works perfectly with the SensoTimer for demand-oriented irrigation control. Application: garden irrigation, flower beds, vegetable beds, hedges, bushes.
