MK2 Din M26 to US conversion

[halocline]

Thanks

I don't suppose there is a way to just add that oring to the MK10?

[COLOR=#000000]It's kind of hard to tell from the photo, and I'm nowhere near home to check one of mine, but if that is a groove (not just a shadow) on the MK10 retainer that is in the same area as the green o-ring on the retainer on the right (presumably the one you took out of your MK2) then it should work. If it's just a shadow, you're out of luck.

There's also a thick plastic spacer that comes on the MK2 and sits between the DIN wheel and the end of the body. While it's not really necessary, it's nice to have because otherwise the wheel is very loose on the retainer when it's not connected to a tank.[/COLOR]

It was worth a try but no luck. It's not a true groove but a sloped ridge. The oring is pushed up the shaft and splits when screwed onto the first stage body.

And I do have the thick plastic spacer from the M26. Should work for the universal (I hope).

Uncfnp,

Is your MK2 an older model? I ask as I was given to understand that newer MK2s readily accept the SP universal DIN. If it's an older model you may not be so lucky. I may get flamed for this, but I would at least try the MK10 DIN by attaching it to the MK2 and slowly open the tank valve or hook it up to a tank that already has low pressure.

If no joy with your new universal DIN, I think AF Diving Doc has been successful in using a Sherwood DIN in an older MK2.

If there's anything I can do to help message me, perhaps I can get the part/s you need?

Thanks couv. I did give it a try but there was a notable leak. If I put an oring in the goove above the threads it worked but only briefly because the slope on the groove forced the oring up the shaft and would split it. If I had the tools I could probably cut a small edge in the groove to hold the oring in place but I don't have the tools or skill.

Its a new MK2 and the universal is on the way. Will update with fit but thanks to Bob's success I am fairly confident it will work.

Thanks Simon. Will let you know if this doesn't work.

I have used the "Universal" SP DIN on my MK-2 with success...

Bob. I need to O2 clean the new Din. It looks like only three orings? And the one on the valve side is white. Do you know the material of this oring?

honestly, no I don't. I wish you had asked earlier as I was at a shop last evening where I could have discussed it. There are quite a few guys who use them for deco.....

Not a problem. I think it might be a polyurethane oring which would be ok to use but since I'm not sure I'll just repalce it.

Done! And it works perfectly. Thanks to all.

BTW best price on Amazon dropped by 10 dollars after I bought mine. Considering buying a spare just to take advantage of the better price.
