Scuba Tech Tips: DIN Regulators and Converters - S04E14

hey divers Halleck Pierce a leap in scuba tech tips now I really appreciate all the comments that I've been getting from all my tech tips first of all it's gratifying that you even watch so I think it's pretty neat I enjoy it I hope you're enjoying it because I'm doing this just for fun you know there's no ads of my tech tips because it's just we're just doing it for fun I don't know why Kevin's doing it cuz I give him such a hard time but whatever anyway thanks for the comments now this particular tech tip today is in direct response to some comments from some of you and the specific I'm going to talk about didn't tanks didn't valves and didn't regular di n di n is stands for a German douche international I look it up di n however here we know the DI end very simply means the type of valve or regular that screws in let me show you what I mean this is a type of regular that most of you have I just have a first and second stage here right this is just a regular eye to make it easier I'm going to take a second stage off that's okay with you like picture that's on there so this is your regulator now your regulator has what we call it yoke style connection most regulators certainly for recreational scuba and those use worldwide use a yoke type connector like this okay and it goes onto a tank just like this so you know very well that this tank has an o-ring in there you can see the old ring if you get in closer together and to mount this regulator onto this valve you simply put the yoke over top of the valve put that round metal piece against the o-ring and just thread it in the back and there you go turn the air on and go diving oh it's wonderful so this is a standard yoke type or regulator now there is another type of regulator that's available let me just show you what that type of regular looks like in order to do that I need to take this out of here I'll explain in just a minute why I'm taking this out of here and because I want to show you a boat so the other type of regulator that you can see that you may have some of you may have is a DIN di n and then is different there's the same type of regulator you see its first and second stage I'll tell you again if you like I can take the second stay by sage off your stick Simone it so we end up with just the first stage because that's all we're talking about we're talking about the mounting system this regulator you see Edwards deal where there is no yolk this is a DIN regulator and this regulator screws into the valve how does it do that well in order to use a DIN regulator you have to have a den valve take a look there keV you see you can see the threads in the valve on the inside then the threads and so what you do is you just introduce the threads and you match them up and carefully turn and sure enough they match and you turn that down snugly against the end and it's not it your regulator is now mounted to the din valve on the tank den regulator din go simple ah there's more to it than that a couple of things first of all let me clear up something that is a common misconception I'd cry oft and often hear this from divers and and it may be because it in Europe den regulators and then valve that connection is most common and and they don't they just don't know very well the yoke type connector the yoke type connector is the original connector it has been like that since the 40s most regulators all through a history used a yoke type connection it's a lot of divers will say if they've been using din they'll say that the din is better I don't like the word better I'd like to work never I don't like the word best with a lot of words I don't like because they tend to be limiting if it's better that means that the other one is not as good and that's not the case at all din is not better then is a seneschal if the pressure is over 3,500 that's all there is to it isn't very simple it's a pressure related matter shear you using steel tanks high pressure high volume steel tanks as many technical divers do now hold a lot of extra air it could be a hundred and twenty 130 cubic feet that's 3500 psi or even higher then you need to have a DIN regulator I didn't connection like this a steel tank at 3500 psi will have this valve you cannot put and not supposed to put a yoke type regulator on this a simple matter of safety and pressure at 3500 psi the o-ring in a yoke type valve could extrude and come out the din or ring is completely captured I know if you can look in there closely Kevin can you see in there but you see the o-ring here in this didn't regular connector the o-ring sits down and is completely encircled by steel the center portion projects and sticks into a hole inside the valve the outside of the o-ring is completely protected by steel so in this regulator if this didn't regulator is screwed in that dim valve that all ring cannot come out it cannot extrude even at the high pressures of 3500 psi that's what the den is for it's not better it's simply required for 3500 psi above if the pressure is less than 3 about run your BS I can though you'll type connector is perfectly fine assuming of course it's all in good shape not badly worn and the o-ring is good and so on and work perfectly fine you can still have problems with din it was not good condition so we'll get back to that so first of all the first thing to clarify din is not better Den is used at 3500 psi and above as a matter of fact it's interesting if you own steel tanks you may have noticed in the last few years that the high pressure steel tanks are no longer 3500 psi they used to be 3500 psi now they're 34 42 psi where did they get 34 42 well very simply if the manufacturer of the tank rated them for 3500 psi and stamped them as co-developer apo sight he had to use the den valve and the diver had to use a din regulator because of the high pressure if it was under 3500 psi you could use a standard yoke valve and all divers worst regulators could use that tank so the manufacturer said hold on a minute if I drop the pressure rating to 34 42 I don't have to put the more expensive din in and all divers can buy my tanks high-pressure higher boiling but they can all use it yo cornet so they put on 34 42 I'd be willing to bet you that the 34 42 is the same tank it used to be 3,500 they just put 34 42 on it so that all divers could use it understand where I'm coming from it tin is only required for high pressure it's not necessarily better know we have a lot of divers used in regulators and they want to have a dim regular some use it for various reasons for the side mounts and and tropone is and variety of reasons or maybe they use high pressure tanks here and you're running sometimes into a little bit of a problem if they go out and they purchase a yoke type regulator a new regulator it'll look like this if they want to use it on their din tank on your 3500 psi dim valve tank they have to change it into a den regulator not complicated but it has to be done properly this is not something you do in your basement garage or ask your brother-in-law is pretty handy with tools to do know the first thing you need to do is purchase the special and it is special is unique to every regulator so this is the right din adapter for this regular that's be the right one you can't just go and pick one they're not all the same this will not work on all regulators then you have to disassemble the yoke system you take off the yoke and when you take off the yoke you end up with a bunch of perks I had them here a minute ago Kevin you might hit them up see you take off to you you take off the screw and you take off the old dust cap and then using there's the screw we take off the knob screw whatever and the dust cap then with a special - you take out the the bolt that holds the yoke and you take that out with a special tool you take that out and you actually end up with all these spirits and you put them away hide the NOI and then you take your din adapter and your dinner doctor then screws into the hole where the yoke used to be and you end up with a bin regular looks just like this okay so now you can use your regulator all din tanks problem salt no or not quite because if you decide to go so if you decide to go to the Caribbean of the South Pacific or somewhere else diving you're going to rent tanks they may not have dem tanks now you have a den regulator but you can't know if you have no den tanks now what do you do well exact this is a lot easier rather you could change it back but you'd have to take it in for service it takes about three hundred inch pounds of force to mount this property and have your regulator's different some require Loctite there is quite a detailed process so rather than taking this into the - or to have it changed all the time simply go to your dice tour and get one of these oh well that's kind of good look this is a yo looks just like a yolk doesn't it so you take this yolk and it screws onto your din regulator and now you're doing regulators a yolk regulator in Ferranti okay okay let me do that again for it if you have dinner regulators or if you change your yolk regulator into it then regulator you're all set that's a special process special part special process okay now you're going to be diving somewhere in renting tanks that don't have den valves on them you could change it back that's going to be expensive take time so go and get one of these or about $50 for a good quality it's a good quality of your a heavy quality din to yolk adapter and this goes on to your dinner a goodish you don't to do anything you have to change your doing regulator at all if now you your din regulator is now a yoke regulator for the onto your yoke valve in the Caribbean where there's and where you go okay simple understand yeah let me show you something else is kind of interesting suppose you do have dim tanks now you may know this but let me show you anyway so you have dim tanks your tanks all have den melts well you may not know this but you can actually get an insert you see this little insert that will go into there into that thread and I see that and with an allen key you put it in nice and tight yet all ring seals in the bottom and now take a look what do we have now that didn't Val there's now a yoke Val so where previously you had to have it didn't regular to put into it now you can take your yoke regulator put it right on there and not get up and go down so you see you can switch back and forth easily here's the only thing you need to be careful of what I just showed you turning a din valve into a yoke valve you must keep the pressure under 3,500 so if you have a tank that's 3,500 or higher you must keep the pressure down you cannot use or ought not to use a yoke regulator at higher than 3500 but there are some options for you you can turn that dingy valve into a yoke valdine internet in regulator and do a yoga radiant turn around you even whatever you want to do is switch them on just a matter of speaking to your local dive store finding the correct adapters figuring out what is best for you what works best for you this particular valve by the way you see me using here is about that we sell only now it should cost about $15 more than a standard valve we called the converter valve if you speak to your local diet or they sometimes have different names or we call it a converter belt because it's a yield now and then with an allen key you pop that insert out and now it's a dim valve for whatever purposes you might need it we call it a converter box about 15 dollars more than a standard belt so if you're buying a new tank you might as well get that on it then you've got those choices I don't know that cleared up some of your questions about din and yoke and and the differences between them I hope it did and show you a few of those options ok didn't vs yoke hope that helped Ali Pearce Ali Pearce
