Tell me more about perm kubi rings on your suit
What's to tell?
I had the non-permanent Kubi rings for over a year. Never had a leak - except for one time when I got a pinhole in my glove. I liked them so much, and I liked my Waterproof D9X so much that I decided to get the suit updated to let me use replaceable silicone seals. So, I had the Kubi rings installed at the wrists and the Si Tech Quick Neck installed.
The Kubi rings just WORK. No leaks. No muss, no fuss to don/doff the dry gloves. The only trick at all is to put a little grease on the O-ring of the glove/wrist joint every now and then. When those O-rings are dry, the gloves are a serious B**** to don. Meaning, the ring of the glove does not want to slide into the ring on the suit. And if you manage it, they don't want to come apart, either. But, with just a little tiny bit of silicone grease once a year or so, they go together so easily you'd think they would pop apart on their own or leak. But they don't.
No tabs to align. Nothing to break. Only O-rings that you'd ever have to possibly replace. No twisting to put them together. All metal (except the O-rings). Easy to don last, right before you get in the water. Lets you keep your wrist seal AND have a dry glove, if you want. Or you could completely ditch the wrist seal and just use the dry glove.
My first time out with the permanent wrist rings, I found a cut in one of my new silicone wrist seals. I was diving the Oriskany, so the water was warm and I wasn't using dry gloves. I was only diving dry for the redundant buoyancy. I had spare seals and it literally took maybe 5 minutes to swap the seal out for a new one. If I had not had a spare, I would have just worn my dry gloves for the dive.
And I really like that the rings are available in different sizes, so you can get the smallest rings that will work for you. I'm 6' 1" and my hands take a size L or XL glove, depending on what kind of gloves you're talking about. Most of my glove experience is with motorcycle racing gloves. I use the 80mm Kubi rings. With medium weight glove liners on, I can just slip my hands through the rings to get them on.
I also like that the glove rings will take generic rubber gloves. The actual dry gloves I use are the same ones that originally came with the rings. Ansell G17K. I think they are 30mil and available in metric sizes from 6.5 on up. My first pair lasted me a full year before they finally got a pinhole. I get replacements from Zoro.com for $2/pair and they will sell them in individual pairs at that price, with very reasonable shipping.
The Kubi stuff is expensive, but it's worth it to me! Simple, streamlined, and reliable.
