I bought a toilet seat bidet that uses hot water from the sink
supply plus cold water from the toilet supply to provide warm water
to the bidet. The bidet came with an adapter to connect to the sink
shut off valve. The adapter is 3/8 inch. It is too small to fit my
shut off valve. I looked at the flexible connector that goes from
the shut off valve to the sink faucet. The label says that it is
1/2 inch on both sides. (Both sides of the connector fit on the
valve.)

I sent the bidet maker an email asking them to send me a 1/2 inch
adapter. I received an adapter today but it was still too small for
my shut off valve. I thought that they had sent me a 7/16 inch
adapter so I went to Lowes and bought a 1/2 inch adapter but it did
not fit either.

How can the 1/2 inch connectors on the flexible connector fit the
shut off valve but the 1/2 adapters not fit? What size of adapter
do I need?

The most obvious explanation is that the connectors on the flexible
hose and the valve are 1/2" pipe thread while the adapter is a
compression fitting.

If the above is correct I don't think you will find exactly the adapter
you want. You might have to put a 1/2" tee after the sink's supply valve.
Then you can adapt one port of the tee to whatever the bidet needs. An
alternative might be to adapt the valve to 3/8" compression and replace
the sink's flexible hose with a (common) 3/8" compression by 1/2" pipe
thread version.

I looked at the flexible connector again and it says on the label
that it is 1/2 iron pipe (something) and 1/2 threaded (something).
(Parts of the label are unreadable because the text is gone where
the label bends around the tube.)

BOTH ends of this connector will screw onto the valve.

Iron pipe is not used for water today, but copper tubing or PEX is. That
changes the whole picture. The measurements on pipe are far different
than for tubing. Take what you have to the hardware store and either a
digital photo or a good description of what exists and they may be of better
help to you.

Sadly, there are several types of fitting that don't fit each other. I
would take everything into a store and ask how to get from one to the other.
Or possibly you have a neighbor familar with plumbing who could look at it.
