Argon Regulators & different fittings

[dom14]

Hey Guys,

What is the difference between below argon bottle regulators/flow meters?!

The bottle end fitting is different in each one and I wonder what/where/how the number 2
regulator/flow meter with its specific fitting comes handy!!!

Thanx

First is for conection direct to cylinder, second could be for a manifold setup.
I wouldn't touch either of them as I don't think the pressure ratings are high enough for the cylinders in Australia. Vaguely remember about 20 years ago we had to replace all our regulators at work because of an increase in cylinder pressure rating. The newer regulators have guages that go up to 30MPa

Thanx mate.
Bit too late for the first one 'cos I already ordered it.

I reckon they are ok maximum pressure rating wise, 'cos pretty much all the regulators I've looked at on fleabay don't go above 25Mpa.
