K-valves to fit SCBA, or Medical Oxy???

Gudmundur 5 April 2005 05:51:55
 Is there a way to attach a K type yoke valve to a SCBA Scott aluminum
cylinder? How about to a B, D, or E type medical oxygen cylinder?
I see the aluminum cylinders at yard sales and so forth, and they are
usually dirt cheap. I was thinking of a low cost pony bottle. Anyone
have an experience to share?

Just in case this is not a troll;

Stop introducing failure points into your dive gear.

There are few worse choices you could make than to use an SCBA bottle of
questionable origin for diving.

If you don't know why that is, you need to take a seat.

I hope you live.

 Sherwood used to make a K-valve that was pipe threaded for fit into a
small oxy cylinder. Don't know if they still do or not. Have no idea
if that valve would fit into the Scott tank.

Scuba cylinders are dirt cheap.

Dive safe,

If you knew anything about metalworking you wouldn't be asking here, of all
places, for an adaptor.

What is the difference in thread sizes?

What will be left of the neck when you open it up to accept a SCUBA valve?

Getting warm?

Any time I see somebody talk about not adding additional failure points, I
cringe. So often, what follows is dogma received from somebody else, passed
on by those that don't have a clue about which potential failure points are
worth the risk, which aren't, or why. In this case, Scott has some specific
issues and the credentials to back them up. He's not clueless regarding the
issues he addresses.

The question, however, that is being addressed does not seem, to me, to be
the one that was asked. The question above, to me, should read "Is there
currently a valve that will fit a SCBA or medical oxygen tank on one end and
a standard SCUBA regulator on the other. Perhaps it would be a good idea to
answer the question that was asked before addressing the issue of adapters.

Once that's addressed, and I have no idea what the answer is, adapters are a
reasonable alternative for discussion. Scott's issues make sense to me;
but, I decline to accept that there isn't an adapter design that will work
just fine, without introducing significant additional failure points. The
connection to regulatorss can be and often are changed between A-clamp, 200
BAR DIN and 300 BAR DIN. If an adapter to hook to the valves on a SCBA or
medical oxygen tank don't exist, I'll bet one could be fabricated that would
be no more or less a problem than the ones we all use now, or, if one
prefers, a suitable valve could be fabricated. I would go so far as to bet,
given access to the right tools, Scott could design and fabricate one
himself.

Perhaps a better question is "Would it be worth the cost?"

I would not 'open it up'. No one is that stupid!!!! That is why I asked
if anyone made a valve that fits!!!!!

Considering how cheap the smaller aluminum cylinders are *and* they include
the valve, I doubt that it would be economically feasible to reuse some
other type of cylinder with an adapter... I had an adapter made for the
European steel-120s that I bought, but it was just so that I could get them
hydroed... It would be possible to create an adapter that would not
significantly increase the failure points, but it wouldn't be economically
feasible except for cylinders that cost a lot more than the ones he's
talking about...
