Impending Tank Leak?

At one of my units, See attached pic of water heater top couplings--really corroded and almost seems to be disintegrating.
Can they be replaced/repaired? Will this leak soon? Or do I need a new tank? Thanks!

What is the age of the water heater ?
Beyond a certain age it becomes more cost effective to replace the tank then service it.

That looks like a badly corroded fitting. There may be a dielectric problem there using the wrong fitting. The fitting in the tank may also be corroded not allowing the fitting to be replaced.

How old is the heater? If it's over 10 I wouldn't try replacing the union and would just plan for the eventual replacement. If it's less than 5 years old I might try replacing the pipe nipple and union. I would also inspect the anode and see if it needs replacing. Yes, there is an odd period between 5-10 years where you'll have to decide which way you want to go.
