LP95 valves

[ibnygator]

I am changing my two LP95s from yoke to DIN and looking at the Thermo 8043 Series with Thermo Pro Outlet and 3/4-14 NPSM inlet. I noticed that there is a 300 bar DIN valve with a 7/8-14 UNF inlet. My question is, how do I know the thread that is on the tank? I looked at the valves on there currently (Thermo yoke valves) and do not see any markings as to thread size and type, nor could I distinguish anything on the tank itself. I purchased these tanks new about two years ago.

I tried searching on this but couldn't find anything directly relevant. Any help would be appreciated...

AFAIK, all LP tanks are 3/4-14 NPSM

7/8" valves are generally used on tank 3500+ psi
