I've seen people recomend not using brass barbs as well, with a an 'all copper' system, not alu. I can understand the reasoning as there is corrosion on my brass barbs (black) in my 'all copper' system, but I thought it was general knowledge the header tanks at least are made from brass?...

As to the copper rad from the dealer, it's diferent for sure but copper?. Dealers stock only original parts, Vendors use any pattern they can find that's cheap...

PS, Also please be careful when soldering heatercores, if their is water inside it will boil and produce steam pressure which can force pinholes in the molten solder!. This is more relevant when repair soldering the fins than when working on barbs but can still apply...
