Hi Lofty
The screw in yolks tend to have the pressure gauge on the cylinder and so aren't used for diving as far as I'm aware, this is info I got from the dive shop that if the cylinder can be used for diving then it is tested as such.
I have a Din fitting which has the pressure gauge attached to the cylinder, if I remember correctly the A Frame cylinders have pressure gauges attached to the hose so the cylinder and can still be attached to a divers regulator.
Although I'm no expert!!!
