Hi I just purchased a 3 way tap that came with 1/2" flexi hoses for each of the 3 holes. 1 hose is for the hot water and 1 is for the cold water. The 3rd one is for the filtered water. I am using an undersink water filter system that connects to a tap via a 1/4" plastic tubing.

How on earth do I connect this 1/4" tubing to the 3rd 1/2" flexi hose so that the water from the filter gets connected to the tap?

I need something to connect to the 1/2" flexi hose on one side and then connect to the 1/4" tubing in the other side. The instructions for the water filter system were based around a separate tap which I do not want to use as I already have a 3 way tap.

It looks like it is a push fit adapter for the copper pipe. In my case, where would I screw my 1/2" Flexi nut to?

Short piece of copper out of pushfit and tighten onto 1/2” flexi nut?

Could do, was hoping there was just simply an adapter to solve it. The second link you showed may just be it although it's a pack of 3 and I only need 1
