Triple Tank, Triple Manifolds!

[hearsejr]

HI, sorry I have been gone so long. I took up sailing and while it is free to use the wind to move you from one point to the other, it does take you forever and a day to get there. lol.
I forgot the specs I had on my system, and about 2 years ago I traded the set up for an outboard motor. to the best of my bad memory I had a nickle plated brass valve. I wish I had taken a few pics, and got more info, but thats hind sight.

How is a 3-cylindered aqualung arranged? If each cylinder is connected to the manifold by an A-clamp on a pillar-valve top, those, plus the regulator's A-clamp makes 4, and when I tried to make a CGI model of a 3-cylindered aqualung where each cylinder had its own pillar valve and A-clamp, I found that the middle cylinder's pillar valve top and A-clamp gets in the way of the regulator's A-clamp and the bit like a pillar-valve top on the manifold that it screws onto. Google search for images of 3-cylinder setups found only http://www.divingmachines.com/vintagescuba.html, which shows setups where the cylinders did not each have their own pillar values but were screw-connected straight to a manifold.

Hi Anthony,

I don't think that there were any commercially available triple A clamp "travel bar" manifolds. I built one quite a while ago vor DIN valve tanks.

Most triple manifolds are like the ones in the link that you posted. Or like here:

Some are with the center tank like in your link but with the outer two tanks inverted, like here:

What you have as others had said is a triple 30 manifold made by USD. However it can be used w and w/o case as the case was made only for a limited time. I just rebuilt another one the other day. Its basically a USD K-valve for 3 cylinders.
It is exact in construction to the current Aqua Lung Military twin manifold w/ exception of no reserve valve. If you look at older era USD spare parts drawings it has same seats seals etc. This triple manifold was discontinued due to high manufacturing cost and general logistics, paying for 3 VIPs/Hydros rather than one. The best way to use these with current BCs is to pass the bc strap around center cylinder for mounting and then use a large strap w/ spacers to secure the far end. The far end strap keeps the assembly rigid otherwise the cylinders have play to move around. This manifold is very durable as it is forged from one piece of brass, unlike the UDS-1 manifold which was made from AL and prone to corrosion.

Hi Folks!

looking for a triple tank system for my ABS System, (3) 30cfi tanks and the triple manifold. Any help would be awesome!

Thanks
Steve,

Old style triples using modern aluminum 30 cu/ft tanks.

Here is a Triple set .. I believe they are triple 38"s. Single hose regulator.
