Seal caps are part of the Kärcher Rain System. They can be easily attached anywhere along the Kärcher Rain System hose and reliably seal off unused cap holes. The rubberized surface and the integrated pin on the inside make this possible. Installation is quick, simple, and tool-free. To use, the pin is inserted into the hole to be closed, and the cap is secured. This ensures that the hose is safely sealed and can continue to be used without unnecessary water waste. The highly efficient Kärcher Rain System operates at up to 4 bar pressure, features a 1/2" hose with drip and spray caps, 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.
