Yoke or DIN with yoke adapter

[potablewater]

If you have any plans to go Technical, then the only choice is DIN.
If your staying strictly warm water Recreational, then go yoke.

All the best,

If the places you travel and/or rent tanks from use primarily yoke then get yoke. While some places may have a few DINs to rent, you are SOL if those few are rented. You can always buy the conversion kit (as opposed to the adapter) for you reg if you later decide you want DIN. Depending on the reg, swapping between yoke and DIN is no big deal and is a better alternative than an adapter.

I completely agree with both of these comments.

Thanks guys, I think that's what I'll do.

I just dont understand the rational behind this thinking.
DIN is better.
Why is DIN to good for rec diving?

There is only 1 reason to go yoke and that is lack of DIN tanks or an adaptor.

DIN is definitely better in ways that are irrelevant to tech v. rec, but not if you have to use an adapter all the time. DIN to DIN is a better connection with a much lower chance of o-ring blow out. If you have DIN regs and are surrounded by Yoke tanks, however, there's not much point. Stick with Yoke. DIN with a yoke adapter is certainly tolerable for a temporary situation, but not long term.

If you're going tech, you have to have DIN. If you're sticking with rec, there's a choice that is determined by the tanks you're going to connecting to.

I wonder what the actual chance of a yoke o-ring blow out is?

I guess it is far less than 1 in 1000... would be interested to hear any diveshop owners who could accurately state the number of blowouts they've had in x years of operation with y tanks a day.

A properly seated, not damaged yoke connection with a yoke sized for the working pressure is virtually impossible to blow out the O-ring.

You get more yoke blow outs than DIN because there are many more yoke connections being used every day and because most DIN users are for the most part more careful (tech divers, equipment geeks, etc.).

I have witness both types of connections blow an O-ring. In either case it was operator error.

Both connections use the same type of face seal and in some cases even the exact same O-ring. The O-ring in both cases works the same. The only difference is the clamping device.

A yoke clamp can be more flexible if it is undersized. A yoke connection is also a lot more forgiving to damage, etc.

I started using DIN fittings over 35 years ago and they are very good, but they are not totally superior like some would like to believe. DIN threads are vulnerable to sand and grit. I would never use a rental DIN tank because you can’t really tell the condition of the back side of the threads (the loaded side) in a DIN valve.

I have seen 3 DIN o-ring blowouts within a 10-minute time period.

Two blowouts were on the same reg -- for whatever reason this particular model of reg, when it first came out, ate o-rings for a living. The other was a very old nasty o-ring on a different reg.

Connections involving o-rings only work if the machining is relatively accurate and the o-rings aren't nasty...and this applies to both yoke and DIN.

As stated before, DIN is by and large a superior connection but if you are traveling to the Caribbean in my experience yoke valves are used almost exclusively. Using an adapter is less than ideal. If you have access to tools and training, you may consider switching the actual fitting on the reg between yoke and DIN instead of using an adapter. Definitely more of a pain though.
