Suunto Quick Disconnect O-ring

[BigDigger]

Hi,
I have a Suunto cobra w/about 75 dives on it and the quick disconnect started leaking a very small amount of air (micro bubbles). After finishing the dive, i replaced the small (3.80 x 1.50 mm, 90 shA) o-ring with the spare that came with the QD. I am having trouble finding a replacement for this critical o-ring. It doesn't seem to be a standard EU or JIS metric size. Any suggestions for a replacment source?
Thanks!

Sunnto dealer maybe?

Where you bought it maybe?

Try Reef Scuba . If you're not sure which one is correct for your application, give them a call or email.

Otherwise if you do find out the size you could try McMaster Carr at www.mcmaster.com they have all kinds of sizes and material make ups.
