Scuba Forum / General / April 2005K-valves to fit SCBA, or Medical Oxy???
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? > Is there a way to attach a K type yoke valve to a SCBA Scott aluminum > cylinder?

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. >> 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?

Unless of course the SCBA is an aluminum luxfer, made after 88, or a Catalina and is 3000psi rated unit. I see people diving with SCUBA tanks every day that I wouldn't use. In fact I would rather use a SCBA cylinder who's hydro history is clearly defined, as opposed to a 6153 piece of sh.t bought from Ebay, and certified by some 'fly by nighter' just to get it out of his shop. >If you don't know why that is, you need to take a seat. Ummmm, being a welder, and having studied metal interfaces, perhaps you could enlighten me as to why a 6160 medical oxygen cylinder would be inferior to a 6160 scuba cylinder if both pass hydro, and both are used within their rated pressure group. Isn't it like comparing a Chevy to a GM? I want to hear the danger of using a medical oxy cylinder within it's ratings. In fact I beg you to tell me the danger. Perhaps I can interest you in some of the 6153 Kidde tanks I had. They passed hydro fine, but I sure didn't want them in my house, or on my back. I'm much to cute to blow up! > >> Is there a way to attach a K type yoke valve to a SCBA Scott aluminum > >> cylinder?

Isn't it like comparing a Chevy to a GM? 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? > If you knew anything about metalworking you wouldn't be asking here, of > all places, for an adaptor.

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?" Lee > Perhaps a better question is "Would it be worth the cost?" 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... >> Perhaps a better question is "Would it be worth the cost?" > [quoted text clipped - 6 lines] >feasible except for cylinders that cost a lot more than the ones he's >talking about... Reading some of the useful input to this thread (yours included) I see that it is not economical, nor really worth the effort. The medical cylinders can be had for damn near free around here, so that is why I asked the question. Figured someone had a one piece adapter for $20, and that may have made it worth the effort. >> >> Is there a way to attach a K type yoke valve to a SCBA Scott aluminum >> >> cylinder?

You insecure Jackass, If we want your opinion we'll give it to you!!! There is no such thing as a dumb question. But there is folks like you who just assume a holier than thou attitude, provide no useful information what-so-ever, and make fun of/second guess everyone else's opinions. How useful is your patented 'get this bullshit out of here' replies?? You burn up as much bandwidth as the spam poster. How useful are your snide comments that provide no useful input??? Again a waste of bandwidth. Give the group un-biased comprehensive answers from verifiable experience. Tell us you are the best master diver on planet earth, and no one else compares to your un-questionable knowledge. I am sure Jesus himself often comes to you with questions that he needs your help with. I am sure you probably made Command Master Chief in just 3 years. Got to admire that kind of talent and dedication. I never faulted any of my blue shirts for even the dumbest question, but I will fault a smart assed know-it-all for not sharing his wealth of knowledge, and in the process, trying to make another shipmate feel small, or stupid. Your snappy comebacks with stupid wisecracks show you are insecure, and afraid that others will see through you, and find you are not as smart as you tell us you are. You may perhaps be a good diver, I don't know, but I bet as a teacher you suck, spending all your time making your students feel stupid, rather than teaching, which would be the job at hand. Continue to show your bandwidth wasting skills and talents, and go ahead and flame me. Truth hurts, and right now you're pissed. Now hit me with what you perceive to be the truth about me. I am big enough to laugh, and don't need the F word to make my points. Thank-you for your brilliant insights, we've all learned from you! >"We're going to rush the hijackers." > -Jeremy Glick, aboard United Airlines flight 93, September 11, 2001 > There is no such thing as a dumb question. f.ck all that.

Unfortunately, there are people who would open up the threads, just like there's people who don't think there's any problem with annealing an Aluminum tank by repainting it with a baked-on automotive-type enamel finish. So for safety's sake, it has to be covered; especially if the question's being asked by someone who's an unknown. -hh PS: local ISP's news server's been screwed up, so I'm not using my regular account.

Anyone > have an experience to share? 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. John > Is there a way to attach a K type yoke valve to a SCBA Scott aluminum >cylinder?

Anyone > have an experience to share? Scuba cylinders are dirt cheap. Dive safe, Cpt. Dale > Is there a way to attach a K type yoke valve to a SCBA Scott > aluminum cylinder? Valve No. Adapt Yes. It's a 2 piece conversion to accept an "A" Clamp (SCUBA yoke) from a Scott bottle. Order a CGA 347 (Male Scott Fitting) and attach it to a CGA 850 (sherwood female yoke block fitting). Fittings are available from any dive shop. Suggest one order by the CGA number only. The CGA 347 has a male 1/4" NPT thread on the end of the tube that will accept the female end of the CGA 850. Conversion done. Easy as 1,2,3. > How about to a B, D, or E type medical oxygen cylinder? Again, you cannot and should not attempt to rethread or change the valve in the cylinder. Order a CGA 870 (that is the pronged yoke clamp that all small O2 cylinders have) or a CGA 850 (what all large 02 cylinders use) and again, attach the latter fitting via male NPT thread to the CGA 850 block. > I see the aluminum cylinders at yard sales and so forth, and they > are usually dirt cheap. ok. > I was thinking of a low cost pony bottle. Oy. It always seems to start off this way. > Anyone have an experience to share? Probably not without being rude and you seem like a nice person. You don't yet see the error in your thinking and that's ok. Many divers think and do as you are doing right now. It seems to be an evolution that divers need to pass through. The conversions as stated will cost around $50. Good luck on the cheap "pony" conversion. -- Randy F.

Good luck on the cheap "pony" >conversion. Thank-you very much indeed!!! This was exactly the information I was looking for. I figured such adapters were in existance, and wondered if anyone ever used them, and why, or why not. I had several 50cf steel 1800psi rated oxygen cylinders that came from a backpack style portable cutting system. The company decided to scrap the project, and the tanks. Sherwood made a valve years ago that fit the standard 1/2inch tank thread. I had several steel 50's done up like that. And always, when I had the tanks hydroed, the guy commented "You'll never wear these out!" And I just bet there is someone who says those steel 50's should have never been set up for scuba either. I don't want to die, or blow up. But if un-modified, and used within design specs, a tank is a tank is a tank. Or so I thought anyway. Thanks for the CGA part numbers, and the insight! Randy F.
