No. for years all that existed were 1/8npt and 1/4 npt. however you have to pull the adapter out of your block as well. in your pic, only the left most one has the adapter.

FYI if you get the brass NPT plugs from either your local industrial supply house, industrial plumbing house, or mcmaster carr or grainger, its even less expensive than home depot

+1 to Scott.

I replaced all of mine with solid brass plugs from local Ace Hardware.
