Can you install a 300 BAR Manifold on a set of LP tanks?

Thomas,

Just about every cave and wreck diver I know uses 300 bar manifolds
with LP tanks. So yes, this is commonly done. I would highly recommend
Halcyon manifolds. They have a 300 bar manifold with 3/4-14 threads
for use with LP tanks in North America and also an M25 metric thread
version. <http://halcyon.net/acc/manifold.shtml>

I don't know what the manifold is, but the last Halcyon setup I saw
definitely had 232 bar valves, not 300 bar ones. They even had the slugs
for using them with a yoke connector, not that any self respecting DIR diver
would be caught using a yoke first stage.

Lee,

To the best of my knowledge, Halcyon has never offered a 232 bar
manifold. You don't have to be interested in DIR to buy a Halcyon
manifold. It is simply an excellent manifold with everything ready to
go.

300 bar DIN valves are commonly used for overhead environment and
other technical diving since they have the most robust connection as
well as having a captive O-ring. For shallow, single-tank diving, yoke
valves are fine, and, believe it or not, are used in this application
by many DIR divers.

Actually, I said 232 bar, but I'm not sure that was the case. I think it
was. I am sure it was not 300 bar both because it was clearly marked and
because it had the screw in slugs that are only available in valves designed
for 232 bar or less. It may, in fact, have been less than 232. As for
having to be DIR to buy Halcyon, I'm not so sure. Since Halcyon applied for
the copyright on the term DIR as it applies to diving, maybe you do have to
be DIR to buy the brand. Previously, however, you are clearly correct. All
of my plate, wing and harness are Halcyon and, were George still around to
ask, he's be only too happy to confirm that I'm not DIR.

Divers Supply offers the same manifold, or at least one that looks
just like it but in 232 bar as Sea Elite. The Halcyon manifolds
without the logo came from Divers Supply. I don't know where the logo
ones come from.

Hi Al,

I've owned 3 of the Sea Elite manifolds from Divers Supply, and they
are fine. However they don't come with same type of rubber knobs as
the Halcyon manifold does, which I would rate as being a bit better.
The Sea Elite manifold is less expensive than the Halcyon and is
available in 232 and 300 bar versions.

They are the same manifold Bob. EE puts Sherwood knobs on them. I think
it was last year DS started getting them from Taiwan with a rubber knob
that looks like the sherwood, but was NFG. Halcyon got these from DS and
had to replace the knobs on all of the ones they sold with Sherwood
knobs, because the Taiwanese knobs wre coming apart. DS replaced them
with the harder plastic knobs. Halcyon went back to replacing the
supplied knobs with Sherwood ones. DS now gets the manifolds from Taiwan
with an improved rubber knob.
