Din to Yoke Adaptor

[jrusso1000]

I have a Scubapro regulator with a DIN fitting and I would like buy a Din to Yoke Adaptor for certain occasions when I have to use a tank with a yoke valve. I have bougth two adaptors via internet but returned them since the adaptor doesn't screw all the way to the bottom of the DIN fitting. It seems that my regulator has more threads than the adaptor.

Do they sell din to yoke adaptors with 7 or 8 threads (not sure)? I thought it was standard but I am realizing that it is hard to find. I am now not sure if it even exists. Is it ok for me to use the adaptor even though it doesn't go all the way to the bottom of my DIN fitting.

I am a new diver and I am a bit confused. Please help.

There are 3 different types of DIN fittings.....200 bar(rare these days), 232 bar(not too common), and 300 bar(very common). The 232 bar has, if believe, 5 threads, and the 300 bar has 7 or 8. If you have a 300 bar regulator(which you more than likely do), then it will not thread all the way into most DIN to Yoke adapters. The adapter will be a 232 bar DIN fitting, since you shouldn't have a Yoke valve on a tank over 232 bar anyways. A 300 bar DIN will work fine in a 232 bar fitting, but a 232 bar DIN will NOT work in a 300 bar fitting.

If the DIN fitting threads in far enough that the O-ring on the reg is sealing against the flat face inside the converter, then it's working correctly. You WILL have 2 or 3 threads visible on the reg.

My Seaquest DIN/Yoke adapter has 300 Bar stamped on it. My 300 Bar reg screws all the way in. You should be able to get one of these from any SeaQuest Dealer. There is a dealer locator on their website.

However, I plan on having a converter rather than an adapter before my next Caribean trip.

Hope this helps

The point being is that it does not matter wheter you use 5 or all all nine threads... the adapter is working fine. The shorter threads on the adapter means it will accomodate ALL types of DIN regulators. There is no inherent risk of breakage ascribed to only having 5 threads used. It can't even start to back out when pressure is applied. Personally, I would opt for the more versatile adapter than the other way.

What is the difference between the two?

A converter replaces the DIN fitting with a yoke fitting, the adapter screws onto the DIN fitting, which moves the first stage closer to the back of your head.

I prefer simply converting back and forth rather than using an adaptor.

I concur with LY. When the adapter is in place I get "VIH" (Valve in Head) syndrome. It takes a minute to change the yoke to DIN or visa versa...

How does one convert from din to yoke in a minute? I just had my scubapro mk 16 converted to 300bar din for my pst hp 100. Now I'm looking into getting an adaptor. I called seaquest and dacor, two dealers I can get wholesale from, and they told me I needed a scubapro adaptor. Logically I knew that any adaptor should work. Now I see this tread. I still have my original yoke parts. What tools do I need, and how do I switch them back and forth in a minute?

one that fits the end of the DIN, and one that fits inside of the yoke and over that nut. One twist off, and then one twist on and I am finished.
