Manifold options

[MxDiver]

One of the manifolds for my ST72s is shot, I want to keep them as doubles. The tanks threads are 3/4, other than buying a vintage manifold are there other options? can a contemporary manifold be used?

will this work? http://www.leisurepro.com/Prod/OMSIM.html I think 3/4 in threads are standard now you sure your not talking about the 7/8 inch threads? I could be wrong here of course.

I measured the threads, they are roughly 1.03" in diameter and has 14 TPI

I think physically I can assemble the tanks. One of my concerns is the service pressure of the new manifolds 3500 psi, the tanks are rated at 2475 (with the +).

notthing that says you have to pump the tanks up that high. How old are your 72's? Also if it is a 3/4 in thread I would not necessarily recommend the oms manifold, also what is the 72's diameter, because that may determine what kind of manifold you need.

I do not intend to pump them that high, but having a manifold with those service pressures, my question was geared more towards the bursting disk as a safety feature, I assume with those higher presures the burst disk would be pretty much usesless on this application.
The diameter for the tanks is 6.8, the original manifold has a 8.125 center to center distance.
I believe the tanks are from 62, the markings read:
DOT-3AA2250
622372 PST
They had the hidro a couple months ago.

First, 3/4 is a standard size so get a contempory manifold will work fine. As for fill pressure/burst discs - thats easy too. Simply change out the burst discs for the 2400+ rated tanks.

As for brands, I have 2 halcyons, 2 dive rites and 1 sea elite. I like the sea elite the best. (its identical to the halcyons but was 1/3rd the cost). I don't care for the hard plastic knobs on the dive rites. (one day, I'll swap them out)

[rox@ucf11]

the dive rite manifolds now have nice soft rubber knobs in contrast the oms knobs are hard

My dive rites are soft smooth rubber.

Looking at the specifications for the new manifolds they all seem to have an 8 1/2" center to center distance. My tanks are set up at roughly 8", can any of the new manifolds be adjusted in, or would I have to get new bands in order to use them?

[rox@ucf11]

thats what I was wondering lol umm im not sure, if the diameter of your tanks is not standard then Im not sure if it would be easy to find a manifold or bands for that matter that work.
