No, those nominal NPT diameters are 14 tpi, not 11.5 tpi like the garden hose.
1, 1-1/4, 1-1/2, and 2 inches NPT are 11.5 tpi, but much larger diameter.And they're all tapered.

Pretty cool / useful tool at McMaster
Replaceable Die External Thread Restorer 2630A12 Tool comes with dies for thread sizes 4, 5, 6, 7, 7 1/2, 8, 9, 10, 11,
11 1/2, 12, 14, 16, 18, 20, and 24 threads per inch. OD range is 1 1/4" to 5".but even a tool junkie such as I wouldn't buy one but I could see the need for such a tool where LOTS of hose were in use. One could chase / clean up the ends faster & cheaper than replacing
cheers Bob
Brand name is usually Gilmore. AND THEY ARE MADE N HE USA< TOO< not China. Come from Pennsylvania, I thin.
I use a pour of cooking oil, (corn, canola, olive, whatever) to lube the inside of he hose. Dip finger in il, liberally coat inside of ose, put more oil n plastic barbed insert and isert.
Great product.

It would require a heck of a garden hose w/ 1-1/4" OD minimum!!! :)
But even if it went to the 3/4" OD, garden hose ends are still thin wall formed, not cut and not as deep as pipe thread. An NPT die of the same diameter would cut through or nearly through the root diameter of a formed NH thread.
Several of my hoses ( the good ones) have heavy brass ends which are cut and look just like pipe threads ... but the are not tapered. 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? :)
lower cost thread restorer?
HD & others make a brass cutoff valve for the hose end. If you use one of them, it will not have to come off the hose - the adapter will take all future punishment rather than the hose end itself.

I just dip the end in boiling water for about 30 seconds. They push right on that way.

Use something like this
This is an old thread, but we may have found the real answer, finally:
Since I got here by googling for just this sort of thing, maybe this will help someone else.

Website won't open.
You're message wont open either. Next time, use a computer instead of that 1940's typewriter you have now.

Thanks for the reply, but the original poster no longer needs a garden hose. In the nursing home he has an unlimited supply of catheters.

Wouldn't be surprised if the die costs more that a new hose section...
These don't look so bad to me. They don't have the stainless hose clamp sticking out. Some of us let nature take its course. I look forward to mid to late summer when grass turns that nice tan color.
