OK, i have to put barbs on to my new heatercore that will fit the 5/8 tubing on the HC and my tubing which is 3/8ID and 5/8 OD.
I was wondering where i can get something that will work and what exactly to get.

If you get brass hose barbs that have a 1/2" npt, the inside diameter of the threaded end is 5/8". Just hacksaw off the bulging ends of the tubes on the heatercore, deburr and clean them, and slip them on with flux, then solder away. JBWeld would work fine too.

I used this on my current setup (soldered).

If you want it purty, you can dremel or file the threads down, and make the fittings look custom.

And Quaky, if it's a heatercore style radiator, it's gonna work fine. Just about any heatercore will outperform the black ice radiators, but they just won't look as nice, and are a tad bit larger.
