Maximum pressure for manifolds

[Drowning]

I am looking into switching to doubles with a manifold and I have the opportunity to purchase a new 200 bar manifold for less than $100. My problem is that 200 bars is only 2900 psi and my aluminum tanks are rated to 3000 psi while my HP steel tanks are rated for 3442 psi (238 bar). So will I be able to use this manifold on the aluminum tanks, or better yet the steel tanks.

:nuke:Yes.

Just install the appropriate burst discs and you are fine.

If anything goes wrong, there's always the accident thread. Good luck!

I'm assuming that your HP steel tanks already have 300 bar DIN valves, so the addition of the 200 bar manifold should be fine. Some cave divers in Florida fill their tanks to 4,000 psi with no problems.

Guys:

Knock it off, this guy is asking a serious question. Your choices are give him a straight answer, or shut up.

You will be fine. Just change the burst disks to the appropriate pressure and you will have no issue at all. The above poster was right, we here in cave country put 3800-4000 in our 200 bar manifolds every day.

I'm so sick of the uneducated fear mongers on this forum.

Yup these are the same guys that will not fill a ( good vip and Hydro) tank that is

older than what 20 years?

Maybe it's because of the way they treat thier tanks.


See you topside! John

You did get a good answer by number three!

I bought my burst disks for my Thermo valves from Dive Gear Express shown above, but the direct link is HERE.

4,000 psi? My regs are rated at a working pressure of 4,200 psi.
