Hi :)
If any has dived..sharm, hurgada or marsa alam....What is the majority of tank valves used there as I (as most of you) would be renting tanks.
Thanks in advance :)

I dove there about a million years ago (or maybe 25) and it was DIN back then...

Based on its proximity to Europe I'm going to guess that it's DIN. If you have a yoke first stage they make adapters that can make a DIN valve usable with yoke, but not the other way around.

Depends on whether it's a 300 bar DIN valve or a 200 bar valve. 200 Bar can be converted (usually), 300 bar cannot.

...... There's different kinds of DIN valves too? what's the difference? can you tell just by looking? I wish I knew this when buying my regulator.

Yes, and yes.

300 bar DIN valves are longer than 200 bar DIN valves... the threaded tube is literally longer. All regs sold today are 300 bar, meaning they have a long threaded tube that will reach the back of a 300 bar valve and seal properly. They'll also reach the back of a 200 bar DIN valve and seal properly... with fewer turns needed to reach the back, and a little more threads exposed. No biggie.

You can see the difference just by looking, although unless you're familiar it may not be obvious at a glance. Outside of Europe, very few of the old 200 bar DIN regs are still floating around. (The 200 bar regs are shorter, and would not reach the back of the deeper 300 bar valve, and thus will not seal.)

Suffice to say if you have DIN regs made in the past 15 years or so, they're 300 bar and they'll work with anything.

oh, ok. whew. Bought my regulator a few years ago and opted for the DIN version. and then I bought a converter.

Thanks for catching me on that Compu. I've heard of DIN converters but didn't realize they didn't realize a 300 bar could not. I'll leave the can of worms on the 300 vs. 200 bar closed though haha.

hmm....... well, I have a DIN with a converter for it... but it's pretty new so is it a 300 bar with a converter for it? If not, is it possible I bought a 200 bar?

Don't mix the terminology up (it's all the same terminology, so it gets stupidly confusing to try to type it out).

200 bar DIN valve, with adapter (my buddies all refer to this adapter as the "Donut") to allow a yoke valve to be used on it instead of DIN (the adapter converts the VALVE, not the reg). This valve can be dove with pretty much any reg ever made (yoke, with adapter in the valve, 200 bar DIN, 300 bar DIN):

300 bar DIN valve. A little hard to see but can you tell how much deeper the hole goes in? This type of valve can't be converted... you need 300 bar DIN regs to dive it. No other regs will work.

This is a "Yoke adapter". It spins onto a DIN regulator, and lets you connect your DIN regulator to a standard Yoke valve on a tank. Technically you could use this adapter AND the donut and attach DIN regs to a 200 bar DIN tank as if it were an all-Yoke system... but that would be silly:

http://www.divegearexpress.com/media/regulators/diverite/RG1225BLK-250.jpg

And finally, this is a Yoke adapter for DIN valves. This is for above-water-use only, solely for filling DIN tanks from fill whips that only have Yoke connectors on them. Two common types are pictured:

So there are several types of adapters/converters for very different (yet similar) applications.... and ALL of them have similar names! Argh!

I have this one (similar at least). I'll take some pics of mine and put them up here so you can take a look.

Ok, here's what I have: (apparently it needs servicing as it is building rust)
Also, it actually says 300 bar on there but you can't really see it in the picture.

Pardon the blurriness. I was too lazy to take out the dSLR so I just used my phone's camera.

Did I just misunderstand you? I thought you said that 200 bar valves can be converted to yoke, 300 bar cannot.
My regulator's interface is 300 bar, and can use a yoke converter. Or am I simply getting the terminology mixed up?

This is a perfect example of the language not being clear. DIN regs, DIN valve, Yoke regs, Yoke valves, adapters for each... which are you referring to? In my sentence, I referred to valves, not regs. The second sentence continued that same thought but could be read both ways if you're hazy on the terminology to start.

200 bar DIN valves can be converted (with the donut) so they can be used with Yoke regs.

300 bar DIN valves cannot be converted to be used with Yoke regs... or 200 bar DIN regs.

DIN regs (either the rare 200 bar or the common 300 bar) can use a screw-on yoke so you can use them with Yoke tank valves.

Thank you for clearing that up. Had to read it twice. LOL

I'm here right now and I have a din and my brother has yoke. No problem for eeither one as the tanks all have an insert in them making them either one. all the guides carry the allen wrench to change them.
By the way we use Saanai Divers in Sharm and Dive urge in Dahab.

Hi. I don't know if anyone fully answered this question. But the dive shops in Egypt generally have both yoke and DIN set ups. In my experience, the DIN tanks there tend to be 200 bar and have threads to convert to yoke with the doughnut insert.

Before you board your day boat or live aboard, make sure the shop knows what kind of gear you have. Some of the shops are more popular with Europeans (especially Germans/Russians, which seem to have DIN gear more frequently than others). If you don't tell the shop what you have, they may be short of yolk set ups once you get out on the water... not a happy day.

Also, you may want to buy a few doughnut inserts yourself and bring them along (you can buy them on Scubatoys). I keep several spares in my equipment bag and they have come in handy many times.

For example, its not uncommon for rental tanks to have dried out, crappy o-rings and no spares on board. Under these circumstances, if the ring leaks or gives way, your dive trip is toast. If you have an extra doughnut, you can simply swap it out, problem solved (its also useful to carry a wrench too -- they're cheap.) You can also just replace the o-ring, if you have some spares too. Just don't forget to take your doughnut out of the tank at the end of the trip.

Hi every body :)
I was just there & they have DIN 200 valves. They also have adapters that you can screw in them making them Yoke but i had trouble sealing my DVT alpha 8 regulator in them. The problem turned out to be crappy O rings in the adapter that faces the inside of the valve. No seal was obtained unless you screw the first stage really hard. The DVT did not allow any air to flow unless it had direct contact & every thing was properly aligned. Thanks for every body who contributed to this thread :)
