I am connecting a water filter to one of my taps. It’s driving me mad. The tap itself has an aerator that is readily unscrewed. The socket on the tap itself is female threaded. Here I am holding the aerator in my fingers and the tap is in the background.
The thread itself is inset a little bit into the tap.
My water filter connector is also female threaded.
So one of them must be converted to a male thread, and the adapter must be small enough not to cause a problem with the narrow space around the female connector that is slightly inset into the tap.
I googled a bit. I found e.g this product decribed as a female to male adapter. But look at it! It goes into the female threaded connector and gives another female one!
What do I need to do the job and get my purifier connected?!
