Make sure you use the right o-ring on your valve!!!!

Apeks DIN regs take a 111 O-ring. A 112 will work but needs to be squished into the groove.

It's metric

Hello, people!
I'm not a diver, unfortunately )), but I use a pony bottle with yoke valve. Could you tell me what is the correct o-ring number (see the red arrow at the picture bellow).
Thanks!

I have found in OZ that some yoke valves take 112 and some take 014 so I have both in my O ring cylinder as inevitably the tank I connect to (not mine) leak and I am fussy about leaking O rings. Went diving in Tonga a few weeks ago and of the 12 cylinders at the shop I replaced 8 O rings (I ran out).

DIN are usually 112 in OZ but I have had no issues to date except having one fall out when setting up one day. Never had a leak or failure.
