Kubi rings leaking badly

[Wibble]

Was your arm wet?

Has happened to me where the dump leaked and it ran down my arm, but not fast enough to notice as the underclothes were very effective. The lower part of my forearm was soaked and I'd assumed it had been the glove.

My arm was somewhat damp as I equalize my gloves with a piece of thin bungee (spaghetti noodle size). But not much.

Not sure if you can with your gloves.
Unless you can fit your hands in to the wrong hand,
make a fist and swap your gloves... if it leaks. On the same hand, probably not the gloves fault...
just matter of elimination glove, oring, suit joint,
Especially if it leaks right a way

Sympathies. Chasing leaks is no fun. I store my gloves in my accessories bag and I don't have any o-ring deformation after a season. But lots of o-rings are deformed and still do their job. Like has been said, test things one by one until you find the failure. I would actually start with completely disassembling the gloves, inspecting the sealing rings for debris or microtears, replacing the gloves (they are cheap, that's why you have extra) and carefully reassembling them. If in doubt about the o-rings, replace them too. They aren't much more expensive. Inspect the inner face of the aluminum on the suit side for scratches. If it still leaks you can eliminate the gloves and move on to the suitside and the Zipseal portion. And so on and so forth.

O rings and gloves have been replaced. Now it’s onto the suit side. Thanks!

I HAD the Ultima. However, they needed more hand strength than I have to lock them on, and they really limited wrist mobility needed for SM. I could never get a hold of my left bungee without an epic struggle. Forget that!

That putty looks like just the job when sitting through some company presentation about how well things are going and how much you're all so appreciated, etc.

Leave the silly string out and do a shallow dive. Use the wrist seal to isolate which side the leak is on.
Or at this point hopefully no leak is found.

I spent several dives chasing down a leak this year. I think I finally found it. Thought it was zipper. Had to turn the suit inside out and pump a lot of air in and a spray bottle of soapy water. Found a nick on the neck seal that was a hinged flap. Didn't see it on visual inspection. Didn't leak on regular pressure test. Inverted suit would open the nicked seal and the flap would let air out. Which is the same as letting water in while diving.

Now get the MRI done on the knee and have some idea what I tore up in it so I can get back to diving.
