Specs are binary. Either the thread can hold the valve well or it can't. If it can't hold the valve at pressure, you'll see leaks of all kinds of severity. Place the tank under water, does it bubble from under o-ring?
It's so "pedestrian" to have to explain the fallacy of this... lol
This is dangerous nonsense. Do you happen to work for the OP's LDS?
You are on ignore. Sorry, it takes a lot, but you qualify.
For those who don't know, what Lowviz is referring to is the fact that O-ring valves are not sealed by the threads... they are sealed by the o-ring. Thread damage can not cause a leak, until the damage is so bad it fails... at which point the leak comes in the form of the valve exiting the tank. The threads are only serving to apply mechanical clamping pressure on the O-ring sealing surfaces (much like the latch on a go-pro waterproof case... the o-ring on the case provides the seal, the latch just keeps all the pieces in contact).
