Thanks, it is pretty well as I suspected. I do have the set of gloves that came with the rings that will work, but I have a tendency to go through these gloves as they get cut occasionally so I was hoping I could use my stash of blue gloves. Turning the glove inside-out is an interesting idea. I am going to try it again with the blue gloves - this time I painted a ring of aquaseal on the inside where the glove should seal with the rings, so I will give that a go and see. \
I also got a response from the company which basically confirms that those gloves won't work due to the inside lining not being able to form a water tight seal.
"Many thanks for your email & questions
We would confirm that the KUBI dry glove system is not recommended with showa style gloves (with cotton fabric inner), as due to the inner this style of glove does not seal within an o-ring system.
This is due to the cotton inner of the glove not being water tight.
We have tried many styles of these gloves and different methods for fixing them, with a variety of results.
We recommend the use of latex gloves or latex gloves with cotton flock lining, as shown on our website.
We apologise if this repose does not give the answer you were afters, but we believe in honesty and offer a wide range of glove styles which we know work fully with our system."
