This kit comprises of a saddle valve device - this is basically an all in one valve which clamps around any copper pipe and self-taps it's own connection. It is ideal for connecting a fridge to mains copper pipe, and can be easily turned on/off for cartridge changes. As well as a saddle valve (which is shown with the 1m of red tubing attached) we include 5m of white tubing, and two push fit connectors. You will require one push fit coupler to join the saddle valve to the white pipe and one to join the white pipe to the fridge itself.
