You need to turn the sleeve inside out, position the cuff ring inside, apply a strong O-ring to the groove, then turn it back outside. If the seal is too thick or stiff that won't work well.
If it does, the sharp bend and hard stretch will work on the corner of the cuff seal and over time it will develop pinhole leaks. You find these leaks pretty easily with a light up the sleeve in the dark, then seal them back up with black contact cement. I've kept the seals going for years this way. You cannot easily used "Smurf" gloves (any kind with a fabric liner) with the OS system, they seep leak. Smooth gloves work fine.
Note - Both the Kubi and the OS are hard on latex seals for the same reason, the hard bend. I found they would go bad in a year at the stress point. You can't patch latex with neoprene cement. Replacement is necessary.
I have tried the SiTech system that uses the small colored rings to press fit inside the seal with the main ring outside. It's a real pain to get the compressible neoprene smashed down. Then it worked fine to 30-40 feet when the water compression made it leak. quite a bit unfortunately. I simply could not get them to not leak. I have no idea how mpenders did it. They work fine with latex seals and are not destructive like the OS, which is a big advantage, and they are easy to put in a latex system. You can use Smurf gloves. The single O-ring seal is a bit touchy to get right but you learn to deal with that.
I see, so it seems that the thickness of the neoprene material is the main factor that makes it difficult. It looks like it is possible to install the Sitech quick cuff system, instructions on page 8 reference a neoprene suit.
