I'm finally putting my tap in my bar, approximately 25' from the keezer. I am planning to use a water cooling setup, but the only thing I want to be sure of is that I don't end up with leaks at the joint between the copper tower coil I'm producing and the vinyl coolant lines in the trunk. Can I generally achieve a water tight connection by just fitting the vinyl over the smooth wall of the soft drawn tubing or will I need some sort of flare or barb? Are compression fittings available?
