Bama it's a thermo 3500 DIN http://www.thermovalves.com/scuba_outlets.htm
the last one on the page. It's a pretty small neck not exactly sure what size. If you have a K valve you think would work at high pressure I'd be happy to switch. Just one question, normally an o ring blows when taking off the reg or just turing it on, or can it blow when ever?
Of course it can blow whenever, but 99.9% of the time they start to leak right when you turn the pressure on. If you get the better o-rings they really will last longer. Then again, if you just buy the cheep ones and replace them every 10 uses or so, you should never really have a problem.
In fact in the 80 or so dives my wife and I did over this summer, we only had one o-ring go, and it was my fault as I tried to turn my first stage when it was already connedted and I ripped the o-ring.
I did notice that a lot of the o-rings go bad on rental tanks, but I think they just use them untill it completely fails or someone complains.
Well I decided to sell the HP100 and just got a LP95. With the plus rating it holds more air and it's acutally shorter but a lot wider. It also quite a bit heaver but less weight on my belt.
OK ... I know this is old but I have been having this same conversation with some of my dealers.
Two years ago (the age of this thread) I was selling DIN filler hoses on compressors two to one over the yoke filler. Last hear it turned around the other way. I started selling tank valves last year and have not sold one DIN only valve but a TON of the cheap yoke/DIN convertibles.
Does that mean that DIN isn't as popular as it once was? Probably not. I think that , in at least in the case of the valves, cheap is the winner ... no matter what the configuration.
I also think it has a lot to do with what people already have. Most regulators that have been sold in the US in the past use Yolk fittings. It is not likely that someone is going to replace a regulator just because they are buying a new cylinder, unless they are buying everything together. I also think you are right cost is a huge factor. I also think DIN is used more exclusively in the technical dive community, which we all know is a rather small percentage of all divers.
It is any easy cure, valve companies now have a valve with a built in adapter! All you need is an Allen wrench! So no matter where you go you can adapt to local equipment. As a world traveler I carry a valve insert so my Yoke first stage works! I think the reason for what your seeing is HPs were becoming the "New thing" and then people started looking at it as hbh2 did and shop owners realized how expensive it is to run the compressor to 4000psi! Wait and see if Cap-in-trade goes through!

I have one of these type of valves on my pony bottle. The only problem with it is that I only have one first stage that will actually fit on to it. It is so wide, that most yolk type first stages will not fit. I can post a photo if anyone doesn't understand what I mean.Originally Posted by Papa Bear
