DIN to Yoke

[Tavi]

Warhammer,
I have an Apex Reg in DIN, I bought an adapter with it. The adapter says Seaquest on the knob. it is 7 thread, and stamped in the metal is "300 BAR". Seaquest should be easy to find or order.

Huh? a 300 BAR a-clamp?

K yeh i did miss the point a little WH but why would someone make an adapter to cover all 7 threads on your regulator. The reason the 200/232 BAR DIN is made with 5 threads is so no mistakes are made and so that you know that its only rated to 232 BAR. So when you goto attach your 300 BAR DIN to a 5 thread valve and it wont go all the way in you know for a fact that its not rated to 300 BAR (not trying to be condescending , just explaining it for other less knowledgable divers). 7 threads no matter where they are, are a sure sign that something is rated to 300 BAR, why make an adapter which would increase the chance of someone making a mistake in thinking that a 7 thread adapter is suitable for 300 BAR. I am a new diver , i hope i dont sound as if i am trying to know it all, i am just trying to understand. Correct me if am am wrong though by all means. Are some A-clamp type connections rated to 300 BAR? Cheers

Why? To protect the threads. It's not the same princable as 232 bar DIN. 5 thread or 232 bar DIN is made the way it is so you can not screw, and have it seal off, a 232 bar regulator onto a 300 bar tank valve. That's the only reason. There is no A-clamp valve that is rated to 300 bar, so there is no chance of screwing an A-clamp adapter onto a 300 bar A-clamp valve. Again, I'm not looking for an adapter rated to 300 bar. I'm merely looking for one that covers all the threads on my 300 bar regulator, while at the same time keeping the overall length to a bare minimum.

Hmm yeh i think i was getting a little confused about an adapter with 7 threads being used to actually fill a tank as well. But still i dont see why someone would make a 7 thread adapter coz it only needs 5 threads with it only being able to goto 232 BAR. I understand what you mean in wanting to cover/protect your threads but everyone i know including the DIR cavers use 232 BAR tank valves with 7 thread regs with no probs.

Hehe....I think you are somewhat confused about what the adapter is. It isn't DIN in any way. It turns a DIN regulator into an A-clamp regulator. A-clamp valves don't have threads. One end of the adapter screws onto a DIN regulator, the rest of the adapter looks just like an A-clamp. So it matters not how many threads the adapter has, cause the A-clamp is the only thing that ever comes into contact with the tank valve. Well it can't have so many threads that your regulator won't seat, but that has nothing to do with it's tank hook-up. It won't work on any DIN tank valve. It's purpose is to allow you to use your DIN regulator with A-clamp tanks. And since A-clamp style tanks can't be filled to 300 bar, then there is no danger in overstressing the adapter or regulator.Here is a picture of one for you to look at. It's over on the right side labeled R239 DIN to Yoke Adapter.

Yes WH thats the adapter i was talking about, so my previous post still applies.

"I understand what you mean in wanting to cover/protect your threads but everyone i know including the DIR cavers use 232 BAR tank valves with 7 thread regs with no probs".

By this comment i ment that there will be threads exposed by definition, you said you wanted to cover them. I was just poitning out that more or less everyone who dives with DIN regs (300 bar) and 232 bar DIN tank valves have no option but to have the remaining threads exposed.
