I have the Kubi dryglove system with Sitech Siflex silicone wrist seals on my Seaskin Nova drysuit. Dose it matter if the shinny or dull side of the wrist seals is against my skin? They came installed with the dull side against my skin.
I'm asking because I'm trying to figure out why my wrist seals leaked a little a little bit. I was diving in the suit using just wet gloves for the first time (all my other dives in the suit have been with the dry gloves). After the first dive I noticed that I had a leak at the wrist seals because both arms of my undergarment was wet up past my elbow (but everywhere else on my undergarment was dry). I've never had any problems when using the dry gloves. I did the next dive with my dry gloves and had no leak.
I just removed and inspected each wrist seal and found a small hole in the left but nothing in the right. I removed the seals, cleaned the rings and o rings, put a new seal on the left, small amount of lubricant on the red o ring and reinstalled everything.
I've never trimmed the silicone seals and they feel tight (but not too tight) against my wrist. The seals lie flat against my skin. I don't have a prominent tendon that pops up when I move the wrist.
Any idea why the leak on the right? Should I trim the wrist seals back a little to see if that helps?
