Any info on the Sh of those O-rings ? Are they all sh 70 Rygar ?

I have the 80mm system and can bring my original GS to work tommorow and see if I can borrow a durometer. I had heard that kubi had sealing problems in the past which prompted them to upgrade to the stiffer red oring.

If you are thinking about putting together kits, I'd be interested. Let you know if you need a tester.
 
I had the original blabk sealing o rings and was lucky if they'd last a season before developing hairline splits around the circumference and would start seeping. The new ones I just got are red, time will tell if they are any better.

Was fortunate enough to talk to Kubi UK and they very kindly sent via Royal Mail, at my risk, but this reduced the exorbitant shipping significantly, they also sold me only what I needed and not complete sets.
 
Yew we are interested in any o-ring products or kits that scuba diving industry need. Let me know the results of your tests and if this is not possible i can give you an address so you can send it to our tech dep in Holland for investigation.Contact me directly please at info@scubagaskets.com

If you don't get what you need, message me. I'd be happy to help if it means I can get these O rings cheaper and more easily.
 
DRIS have the spare oring set in stock, at least for the 90mm, and they are selling them for $20. (ƒ14.4)

Pretty reasonably price give the shipping charges that I can find on the European sites are all pretty high now. They sell for GBP10 and shipping is like GBP20.
