Nipples at top of water heater?

[voight]

The attached photo shows a nipple at the top of a water heater. It appears to be aluminum. It did not appear to be galvanized. I know you have to have a brass diverter fitting or a dielectric fitting between copper and galvanized pipe. What about aluminum and copper? Does this appear to be an aluminum nipple?

That looks to be a standard dielectric fitting and is correct.

I concur with Chad. Looks fine to me.

Chad is correct. One of the things that help identify it is the dimple or recessed area in the center of the fitting. MOST fittings that are not dielectric do not have that dimple. I said most because last year I saw a straight sided dielectric fitting in the big orange box.
