Odd ball valve for smart toilet supply

[lubemonkey]

Hi,
I'm fitting a smart toilet and it comes with an angled ball valve with filter for regulating the water supply. The flexi goes on the outlet part fine but I'm a bit unsure of the inlet side. It has a ribbed thread and no nut. A standard compression nut and olive will fit onto it fine, but it has a flat end with no internal bevel to help with squeezing the olive.
Unsure on how to fit to 15mm copper as I've not seen a compression fitting like this before. Is it even a compression fitting?
Cheers, Lubemonkey.

It isnt for an olive fitting.

So one of these plus some ptfe should do the trick?

That looks like a fitting for what is commonly known as a bum wash gun rather than a smart toilet.
