: : Can you explain to me what a Dielectric Union is? Would a brass nut at the end of a flexible copper tubing be considered a "dielectric union"? If not, what would be considered a dielectric union.Thanks,Gordon Gordan, Water heater flex connectors have a brass nut and plastic or nylon (I think)that seperates the two metals from contacting. This breaks the electrical current between the two metals. At least that would be the theory. You will still find corrosion at dielectric unions so some electrical currents must be passing through the water. Terry
