Since I got here by googling for just this sort of thing, maybe this will help someone else.

These are the ones I wanted to re-thread.

I've never seen a garden hose w/ that style an end--have a bunch of the
NPT to NH brass adapters which are, but not on the hose itself. Wasn't
considering that possibility and didn't get that from the original post
(obviously )...

In that case, however, I can see the point and can understand them
getting munged up more than a regular garden hose. Guess there's no
free lunch, is there?
