din conversion

[tomboyy]

Do I need to Torque my DIN consersion kit or can I tighten it like it would my hoses and regs .
I asked in another thread and just wanted to get more response.

Thanks !

I always tighten mine hand tight and it good

I would want to refer to the tech literature for that one. I would think your answer would be listed in the regulator's service manual that you can find online.

The Scubapro torque spec on the Mk25 din retainer is 266 in. lb. That retainer does not have to loosen much for the O-ring at the bottom to become useless.

You need to follow the torque specs according to the reg. This can be anywhere between 30 to 40 nM or around 22 ft.lbs. Overtorquing can lead to cracking of the reg body, while not enough torque (ie hand tight) will lead to improper sealing (some bubbles). Personally, I don't think that the reg will fly off an undertorqued nut with 3000 PSI of force, but that's just something I'm not willing to find out.

On my Aqualung Titan I used a "fair bit" more force than hoses, and it still came loose a few times - it would wiggle around as I was fitting it to the tank. So I used more force. It's been fine for 30 dives or so. On the Apeks DS4 I applied more force than for the hoses (but it didn't seem to be as much as the Titan) and it's been solid for 15-20 dives or so. Test your gear and bubble check. Don't crack the body or smash o-rings!

All measures are metric.

On just about all regs, the one torque specification given in the service manual, is the yoke nut and similarly the din fitting. Generally they are specified to a torque of 25 - 34 Nm, depending on the brand. Scuba tools has a torque wrench in this range for just this application.
