I was thinking of installing this handheld bidet
https://www.amazon.com/dp/B07CMX71JQ in the side of a vanity.

The specs say that the inlets are G 1/2", the Asian/European version of
FIP, aka BSPP (non-tapered)

I have two supply lines from the sink valves (3/8" NPT (female) to 1/2"
NPT (female)).

So apparently I need a G 1/2" male to NPT 1/2" male adapter as well as
the seals that are necessary.

Am I missing something here? I can't understand how so many people have
installed this in the U.S. without running into the need for the BSPP to
NPT adapters.
