Coyote Radiator hose barb

[Junbug]

So I'm connecting my radiator to the aftermarket expansion tank I purchased. I understand that I need to purchase a hose barb to replace this petcock. Anyone know what size threads and what size the barb needs to be?

I used this one - 1/4 NPT male threads to 3/8 hose barb: https://www.amazon.com/dp/B0B9M1HH6C?smid=A3C84HZWTTKSOR&ref_=chk_typ_imgToDp&th=1

I used this. Chrome plated, as if you can see it when assembled.
