New OMS Bladder threading?

[DiverGuam]

The older OMS's used Zeagle threading on their BCD bladders, but the new ones use a coarse thread (like Mares and Aqualung, but not matching.)

Whose threading do these bladders use?

(cross-posted the BCD discussions, but maybe more a DIY question, so)

I have a Zeagle Express Tech and it has the course threads. My OMS, which is a current model, has the fine threads. Maybe Zeagle used to be the fine threads but is now the course threads? It's difficult to put a name on it because I recently bought some generic dump valves that are the course threads.

When did you buy the OMS bladder? Is the bladder connection point glued to the bladder or pinched on? The newer ones are glued to the bladder, while the old style were pinched by a two piece connection point.
