Since this probably won't be deleted, I believe 1/2 or even 3/4 barbs can be used with 1/2 tubing. From what I've seen around, in some situations if the tubing is warmed you can stretch it over the 3/4 barbs and when it cools it makes a pretty good seal.

for 1/2" ID tubing the min you can get is 1/2" OD barbs.
Go for 5/8"OD or bigger and stretch that tubing a bit.

I doubt you will get 1/2" tubing onto a 3/4" barb. however 1/2" on 5/8" barb is cirtanly possible

It's possible. Difficult- VERY difficult, but you can do it if you are as stubborn as I am.
It really isn't worth it though, as most 5/8" barbs have just about a 1/2"ID and if not, they have enough material to carefully drill them to a true 1/2".
It is much easier to make a 5/8" barb with true 1/2" ID than it is to get 1/2" ID tube over 3/4" barbs.

I agree with RD that it can be done, it should be noted some tubing is more elastic than others, For example vinyl tygon is pliable, if your think your going to stretch 1/2" vinyl 'reinforced' tubing over a 3/4" barb it 'ain't gonna' happen
