Is Din adapter Madatory for High Pressure tanks?

[SuSexFulDiver]

I purchased an Aqualung Legend LX ACD regulator, and I am planning on buying a couple high pressure tanks, Is it madatory I get Din Valve adaptors for the regulator? If so where can I purchase the adapter?

most (most) yoke valves that will not stand a high pressure cylinder (3500 psi) will be so stamped, limiting their use to 3000 psi fills.

however, modern yoke valves will handle a high pressure tank just fine

you don't need to get a yoke-to-DIN adaptor unless you want to use tanks with DIN valves. here's one such adaptor:

Are you sure about this?

The o-rings doesn't used to last long based on my experience. I mean when the pressure is over 3500 psi....

 

[H2Andy]

oh, i'm not sure about over 3500 psi... but to the tank's rated pressure, yes, i think so

anyway, that's what i'm told

i'm pretty sure that the highest rated pressure out there (for mass production tanks) is 3500 psi, which a yoke valve will handle fine

Just to be a pain in the ***, I think most of them are 3450

a pain in the what?

i don't follow, i'm sorry.... could you spell it out for me?



actually... i remember now that there's a tank out there rated to like 4400 psi ... but can't remember who makes it

wow, I know I was reading there were some companies looking at putting out wrapped fiber tanks in the much higher range, closing in on 5 digits, but the problem is 1st stage regulators to keep up. They are already using super HP tanks like that for some firefighters though i'm told.

My HP 100's and 80's are rated at 3500......(+/- 10%) 3800 fills..........not that I WOULD DO SUCH A THING...........

There's also the problem that they would be something like 20 lbs bouyant.

As I know, HP tank doesn't have ......(+/- 10%) thing. It is only applied to LP tank.

What brand of tanks do you have?
