As far as I know the adapter screw is conical on one side and flat 
on the other ,threats are the same on both sides. If you srew it in 
the wrong way you are sc***d and you get a hell of a leak.
It will not only mark Greg car's territory.

Good point, that's the difference between a pipe thread and a compression
thread.  Actually I thought that one was 28 threads per inch and the other
was 27.  Certainly close enough that it will screw in 1/4 inch without a
problem.
