heater coolant tubes

I did a single aluminum pipe for the front line on my Stealth intake. It has a rear water cross-over so one of the two hoses connects back there. Here's the only picture I have handy showing it. I think I got the pipe from McMaster, but don't recall for sure. I just sanded it with some 1200 grit paper and sprayed it with clear.

yeah, i have looked at the HD too. they sell a copper pipe adapter that you can braze to copper tubing that gives you a 1/2 inch female pipe thread. then you could screw in a 1/2 in brass fitting with a 5/8 barb so that you could connect your hoses. but now your talking about a LOT of potential leak sources.

my other thought is to use an old set of needle nose vise grips and put a crude bead roll on the end of the copper tubing. seams like the best solution so far. other than just using the stock 5.0 heater tubes anyways.
