Thank you so much for the thorough but easy to understand explanation of the differences. Now I just need to figure out how to tell them apart without a caliper.
everywhere I look it is telling me that GHT is also the same as NH? is that accurate? I have shellfish dealers trying to put a back flow preventer that supposedly has standard hose thread and requires a spigot or adapter with "at least 4 NH threads," onto their sill cocks but it is not fitting... and I'm not finding a GHT to NH adapter... other dealers have used a GHT to NPT adapter somehow and got it to work but that same trick has not worked for others. I'm sooo confused... annnd so are the plumbers dealing with this lol.
Hi, NPSH stands for National Pipe Straight Hose thread. It has the same threads per inch as National Pipe Thread (NPT) but the threads do not taper. This allows a female coupling to thread onto a NPT fitting without being a permanent connection. We are not sure what NPSC thread is, and cannot comment on what the connection looks like. Thanks
Finally found the right information all in one place! Thank you

Ty, wish I could find a compatibility chart.
Very useful information

Thanks.too good
Are NPSH and NPSC the same thing?

Why the fuck are different threadings used?!!?
