Can you please confirm valve threads ?

[Bob DBF]

There is no other modern valve threads in inches after the 1/2" NPT (or is it NGT ?) of the sixties, right ?

There was a short-lived 1/2 NPS thread used for a time by a couple of tank manufacturers, but the competing 3/4 NPS thread became the industry standard.

Hello.
Anyone with a valve removed from the tank at the moment; can you please measure the thread in your valve, not what the documents/specs may say/show on a web site link ? (a parallel one, not tapered)
Is it 0.700" or 0.740" or 0.750" or 0.875" or other ?

Got it.
To post #3, diameter is 26 mm, or 1.02"

How does this post relate to Post #3?
