Tap Connecting, need a little help?

[Dan Brown]

Hey all, i got my friend to come over and check my tap after i had a little problem with it (he fixed the problem) but he also recommended me to get a tap connector that is 15mm x 1/2". No clue what this is? But either way i went and had a look around the interwebs and found this one that has the same 15mm thing ( https://www.ondemandsupplies.co.uk/products/15mm-x-1{47}2"-Flexible-Tap-Connectors-%2d-300mm.html ) anyone have any clue how i will be able to attach this to my tap(s) or shall i bring in my friend again haha.

Thanks alot in advance, no clue about this tap business.

P.S: I posted this in the general diy "tab" because i didnt think it would go into any else, apologies if i was wrong and i will swiftly move it somehow and go to the correct "tab".

15mm is the diameter of the copper supply pipe, and 1/2" is the thread size of the brass tap.
Flexible connectors are shown in your link, and compression and solder types are also available.

Would be helpful to know why it's needed?
