As a result of putting the quick-change wrist seal system on my suit, I had to give up my beloved Viking bayonet rings, and go to the SiTech system (not the Roll-lock, the one that slides into the outer ring). I had a horrible problem getting them on and off, which has gotten better (but not good) since someone gave me the advice to lick the darned things before donning. But I've got another problem that's baffling me: When I put the glove side into the suit side ring, the o-ring is coming up out of the groove and getting pinched. Sometimes it's bad enough that I can see it happen and fix it, but other times, it's not visible, and I end up with a wet hand.
Has anyone else experienced this, and do you have a fix for it? (Any advice on getting the blasted things on and off without requiring help from your buddy would be gratefully accepted, too.)
Thought I'd update this. My gloves have recently started to seep badly. First one, now both. I just ordered 50 of those McMaster O rings, so we'll see.
Update: I've had to use my backup suit for several weeks now (the one with the SiTech rings). Using the smaller o-rings, and carefully licking the glove rings before installing them (all the while wondering what kind of ghastly gastroenteritis I'm going to end up with from doing it) has resulted in no pinched o-rings and no leaks. I still find the gloves more difficult to get off than the Vikings, particularly if one is not utterly meticulous about keeping them free of all particulate debris, but I don't hate them as much as I did at the beginning.
Yes, the ones listed earlier in this thread (9452k174) O rings. Once they get here, I'll post.
I use some silcone o ring lube for them, makes getting on much easier.(Trident stuff).
Dont forget afterwards to unscrew the rings 3/4 turn, and reseat the rings. that step is pretty critical.
The Orings do get worn out, as I found the new ones took alot more pressure to get on, even with silicon lube.
