Thanks a lot doctormike....by chance would you have a Youtube link showing the installation procedure (which glue would you use?)...appreciate your feedback...!
I wouldn't glue it yourself, unless you have a lot of experience working on dry suits. You basically make a choice:
1) Wrist seals are glued to the suit, rings are non-permanently attached to the sleeves.
Advantages - easy to do yourself, and if you really don't like the system for some reason, just take it off, you are only out the cost of the rings, which isn't much.
Disadvantages - If you rip a wrist seal, you are done diving until you can get a shop to repair it.
2) Ring glued to the suit, wrist seal trapped between the two rings.
Advantages - if you rip a seal (common), you just grab another one and pop it in, 5 minutes. My preferred approach.
In either case, the rings provide the bulk that lets you pull those cheap pullover gloves on and they stay on during the dive. No fancy connectors or proprietary latch mechanisms. No expensive bayonet devices that often jam or require assistance to don and doff.
And if you tear a glove (very common in wreck diving), you can just throw it away and grab a ($13) replacement from your bag. Don't need anything special with a dedicated connector mechanism.
Here's a video for method 1. I prefer method 2.
