Can I use these for the zomee z2?

I don’t own the zomee but I have tried these with several different pumps and these inserts can pretty much fit universally into any 24mm flange.

I measured for a 17mm flange. According to the sizing chart I would order a 19mm. Is that correct?

That is what I did and ir fit very well. I can use them in my willow go and my momcozy s12 pro!
