The heatercore I bought off of e-bay uses 5/8" inlets and outlets. I have no access to a welder so I'm looking for other options. Its clearflex 60 so it has some give. I was thinking about dremeling off any extra length I don't need, and then bending in the cut to prevent any rough edges from cutting the tube. Then soaking the tubing in hot water and clamping it on. Good idea, bad idea?
