Will this 1st stage work with a HP steel tank?

[chilie]

Hi everyone, sort of a NEWB question here, but I know my limits and I know when to ask for help. I have a Zeagle 1st stage and prominenelty marked on there is 232 BAR. I am wondering if this is ok to use with a HP steel tank. The conversion from 232 Bar is about 3365 PSI. The HP steel tank is rated for filling up to 3442. Is it ok to use these two? or will I need a new 1st stage?
Thanks in advance everyone!

I think Spectrum had said something to the effect that 200 BAR manifolds can handle 3442psi? Right Spectrum?

My problem with my HP tanks, is, irregardless of how I begggggggg them to give me a good fill once in a while, then can never seem to squeeze in more than 3250 psi.... That is 3 different dive shops!!! My guess is that the safety margin of a reg's first stage is likely at least 1000 psi higher. The O ring will blow before the reg will.

I dive with my Zeagle Envoy Deluxe and my HP 120 (3442 psi) all the time without any problems.

3442 by definition isnt high pressure.

You're parsing terms with Din vs. yoke and HP vs. LP vs. 'standard' pressure. Tanks sold with a combo yoke/din valve are NOT high pressure. High pressure tanks only have DIN fittings and start at 3500PSI.

Any time you use any piece of gear beyond what it is certified for you are running a risk, it's not something that should even be considered in my opinion.

i think you can do without that 80psi! don't you think so?

You'll be fine. Would you be happier if the reg had 237 BAR stamped on it? (3442/14.5)

The pressure on the reg is nominal/operational not maximum pressure. 5 bar more or less is not going to harm it.

Tell them to adjust the supply regulator..............

I think most HP tanks now a day are sold with a 3442 psi rating. Few are with the 3500 rating. As Spectrum noted, it is to keep it just under the modern Yoke's capability. I think he said at 3500 and above, you'll have to go with DIN.

Irregardless, most ads I've seen for HP tanks are now saying it is 3442. I'd suggest you do a google search for HP scuba tanks, I'll bet most of them are 3442 and not 3500.

Many HP tanks today are sold with a combination DinYoke fitting. They are set up for yoke, and you can unscrew the yoke fitting with an alen wrench when you want to use din only.

All HP tanks in the US are required to have DIN valves (DOT Regulation).

It's a marketing ploy, nothing more when a tank is marked 3442. It's no different then a yoke tank rated at 3,300PSI - that isn't a HP tank either.

Still parsing terms....

Still, find me an HP tank on sale that is rated 3500psi, and I'll find 5 that is rated 3442.

I don't know enough about tanks.... Just that every HP tanks I've seen in shops are rated 3442.... And the same with tanks listed online.
