My tank came with a threaded adapter that fits in the neck of the bottle, to allow either DIN or a yoke type to fit.
The reasons I hated my yoke type:-
1, I work with compressed gas, at a much lower pressure mind, in my view this isn't as positive a seal (to the bottle) as the DIN type.
2, the pressure relief screw was always stiff as hell to move when under pressure, I used to have to use pipe grips to turn it, and I had to wind it some 3-5mm out before it relieved the pressure, even when it was only closed finger tight.
3, I dislike the design, the part you screw, to secure it on to a bottle, mine was pointed. I wondered if it would do damage to the bottle I should not have worried though as the point is now rounded off.
I got my yoke type free with my jack kit, so it's probably a cheapy one. It's now a paper weight, as it's all its good for in my view.
I bought the DIN type, and it's a much better system, it's far more positive sealing, a better design and safer (in my view)
