Go Din or go Yoke Adapter Question?

[diveprof]

I am also a DIN fan. The big draw is a lower profile (reduce entanglement hazzard) and a captured o ring system less prone to failure. I used to add that you could use higher pressure steel tanks, but this advantage has been somewhat put to the wayside ('cept for those really overpumping their tanks) as the 3442 psi steels can be used with yoke regs.

I was rereading this thread, causing me to rethink my regulator setups.......

As I mentioned before I have a single tank DIN setup for local diving and a Yoke as my travel reg.........I own both LP and HP tanks..........

I am considering consolidating to one Yoke single tanks setup........

It was mentioned that a SP MK2 could be used up for HP tanks........

From the SP website.......

MK2PLUS......

The SCUBAPRO ÅØorkhorse? MK2PLUS was first introduced onto the market in 1962. This classic downstream piston remains as popular as ever, especially in schools and training centers. The simplest first stage piston mechanism ever, with fantastic performance and easy maintenance. The MK2PLUS comes in a very compact design for a simple and reliable package that remains unmatched.

Classic downstream piston- The best example of bulletproof reliability and trouble-free, minimum maintenance regulators. The classic downstream piston configuration is the simplest mechanism that exists to control the pressure drop from a tank to feed the second stage. The classic downstream valve is the first choice of diving centers and rental facilities worldwide for warm and moderate water temperatures.
DIN/INT first stage configurations. To ensure worldwide compatibility, all SCUBAPRO regulator systems are available in a 200bar INT version as well as 300bar DIN versions.

I added the bold underlining..............

I also checked Zeagle, Atomic Aquatic, could not find any info on the yoke rating itself and if it was OK to use the Yoke for HP tanks.........

I know that many HP tanks come with combination DIN/K valves, but when I ask my LDS about this I get told - no you can't us the Yoke for HP fills, it is only an option is you under fill the tank........???

I am not sure that the LDS is correct.................

Thanks........M

. . . Atomic Aquatic, could not find any info on the yoke rating itself and if it was OK to use the Yoke for HP tanks.........

The Atomic Owners Manual gives a max. pressure rating for the yoke (all models) of 3500psi (241 bar).

I have personally used a yoke regulator on a HP80 tank without issues. I am not suggesting you do this, rather follow the manufacturers specifications (in the case of the above mentioned regulator 200bar/3000psi).

The best advice I can offer you is to evaluate your goal in diving (rec, tech, cave) and where you will be diving (availability of proper tanks w/valves). If you plan on transitioning to tech diving you would be better off buying a DIN reg. If you plan on travelling to places where DIN tanks aren't available and conducting recreational dives then yoke may be your answer.

I have complete DIN for my singles and doubles right now......

I also have a Yoke to travel with.........

If I can do HP with a Yoke then I can streamline my regs by one setup..........

7 regs is too many........

I've been using Zeagle Flathead DIN which originally came with DIN yoke adapter, was worying about the head clearance problem but never had it happened. The adapter does not really interfere. So if you do not have this problem I think DIN has more potential.

I'm a fan of DIN regs. When I travel, I toss in the converter. For the most part, the shops have either some tanks setup for DIN or convertable valves. Either way, I've never regreted going 100% DIN

 

[diveprof]

I agree with the above. I was happy when I went DIN over yoke and never looked back. I was happy when I went steel tanks over AL and never looked back. I was happy when I went BP and wings and never looked back. I was happy when I stopped chasing women half my age and never.... hey 3 out of 4 ain't bad

If the yoke is rated for 3500 psi on the Mk2, it should be marked. However, if you read a little farther on the Parameters tab for that reg, you will see the yoke is rated at least 232 bar or about 3410 psi. I don't think I would worry about 3442 versus 3410.

Over at Dive Gear Express they have a page about buying tanks that includes a discussion of Yoke and DIN valves How to Select a SCUBA Tank - Dive Gear Express Their point of view is that if the yoke is marked 3000 psi or unmarked, they would not recommend using it on a high pressure tank.

Basically, that's what happened to me with the Oceanic Omega II's. The yoke was clearly marked 3000 psi and the tank is clearly 3442 psi. Almost 15% difference. So, I converted the regs to DIN. Now there is no question because the DIN fitting is 300 bar.

I think you still have reason for question. While the din fitting on you regulator may be 300 bar (7 threads), I suspect the din valve on your tank is only "200 bar" whicyh is only 5 threads.:shocked2:

So, are you feeling lucky...are you?
