Loose spout on pull out tap

[Greg234]

Hey all, my wife recently bought a pull out tap for the kitchen, much to my dismay as I was the one fitting it.

the problem is, the spout is really loose. I disassembled the spout only to find it’s on a thread without any o rings at all. So basically it seems like when you swivel it, you are actually undoing the thread that holds the spout on.
Has anyone come across this before? They are sending a replacement but I can’t see it being any different .

thank you
