Does this have 1/2-28 internal threads and 3/4-16 external threads?

Answer

No. This sizing you see is NPT, typically used for Natural Gas pipe. National Pipe Thread Taper (NPT) is a U.S. standard for tapered threads used on threaded pipes and fittings. In contrast to straight threads that are found on a bolt, a taper thread will pull tight and therefore make a fluid-tight seal. The Thread Pitch of 1/2" NPT and 3/4" NPT is 14 TPI (threads per inch). The Pipe Nominal Outside Diameter is 0.84" for 1/2" NPT and 1.05" for 3/4" NPT.

The fit was perfect with no leaking. I needed this bushing to enable the installation of a faucet. I used teflon tape on the threads. As with any iron pipe, I expect that the bushing will rust over time.

start rusting after 2 days so it's not healthy to use the water for drinking or cooking.

Most likely not
I think the 1/2 is 1/2-9. It's no more than a 13. If you take standard 1/2" bolt the threads will not match in spacing and your best bet is to go with a smaller size and rework it to the right size. But you are much better off looking for something that is special made,it will end up a lot cheaper. And what could you be do to need threads that are so tight.
