PTFE adapter for MK4 nextruder

I see the nextruder already has a threaded hole in the top. What size threads are those? Can I buy an off the shelf connector for attaching a PTFE tube? (Or order just that part from Prusa? I think it is part of the enclosure kit)

I'm guessing these would probably work (and won't take as long to arrive or cost as much shipping as ordering from Prusa :-).

https://www.amazon.com/dp/B01N6JF205/ or I could get an actual festo part from digikey for slightly more money and time delay.

Yes, I think so. The part does not have to bear a big load and I always screw it in and out with my fingers when I change filament, because it is easier that way.
