Well there is an O-ring.....
It is located on the depressing pin in the Reg!!

So these MFR compatible valve seal on this "Internal" O-ring!!

Also FYI... the difference between the valves is the diameter of the opening of the valve!!
(https://photos.imageevent.com/scl_electronics/gun/air/websize/bottle%20valves.jpg)
The opening is larger to allow the O-ring to fit and seal.. As it open the valve!!

There's been some info on here about the threads on some BF components; valves, reg testers, QF etc where the threads are a very tight fit when matched to Theoben components.
I've had a couple of second hand bottles where the the valve threads have been very tight for the bottle adapters. May have been BF valves on the buddy bottles???
