Yeah, at the time I wasn't aware that there were two different models of Pas lite 2216 psi being sold in the U.S.(I presume
@GasMonkey didn't know that either).
I'm not sure where he got that info about the different coloured ldv valve buttons being positive pressure versus negative pressure. It seems in this case they're being used to differentiate the two different Pas lite models in the U.S.?
That adapter looks male on both ends. You need one with a female G5/8" connection on one end for the 3358743 model male connection to fit(at least going by that model's pictures).
Like I said in a previous post above, you could use the U.S. adapter used in the SCUBA method instead. It has a G5/8" connection on one end(female), and a CGA580 bullnose male on the other.
However, on the SCUBA megathread, people had trouble sourcing it initially. They firstly were only able to find an adapter from Aliexpress, with G5/8" on one side, but flathead CGA580 on the other(i.e. not bullnose):

I'm not sure how tight that flat-head side of the adapter secures into the cylinder.
People then found a European website(that shipped worldwide) that sold two parts that could be put together to make the adapter:

However, a few months back they ran out of stock for the parts.
Then different parts were found on separate U.S. websites, to again be able to screw together to make the adapter. :

Someone who bought the above two parts said that they didn't screw together fully (there was some threads showing). I don't know if that mattered in terms of if gas leaked from their connection or not.
