MadDogMe,
i'm with you 100% on this one...
i hate barbs...
first of all they cost like 1.5$ each then u have to make a tread (which is PITA since the diameter is big) and after all that they have such a small ID....i use copper tubing all the way...cheap and the ID is almost the same as OD cos the walls are very thin....
just solder and off u go...

and yes 99% of ppl use them.....:shrug: hmm...ppl are not thinking themselves they just see a design and blindly follow it....
sorry to get away from the topic....needed to express on this one....
