Seal sleeves are part of the Kärcher Rain System. They can be easily attached anywhere along the Kärcher Rain System hose and reliably seal off unused sleeve holes. The rubberized surface and the integrated pin on the inside make this possible. Installation is quick, easy, and tool-free. The pin is inserted into the hole to be sealed, and the sleeve is closed. This ensures that the hose is securely sealed and can continue to be used without unnecessary water waste. The highly efficient Kärcher Rain System operates at pressures of up to 4 bar, offers a 1/2" hose with drip and spray sleeves, and combines the advantages of micro-dripping and traditional irrigation. The Kärcher Rain System can be individually adapted to almost any garden and works perfectly with the SensoTimer for demand-oriented irrigation control.
