Dry Suit Zipper???

[xjeslesx]

Hello, I have a DUI CF200. My zipper is starting to leak at the rubber boot on the bottom of the zipper (where it shuts). Has anyone else experienced this type of slight leak? Have any suggestions for how to stop the leak? I've tried to add wax to the boot to see if it would seal, no luck. I'm considering laying a strip of aquaseal inside the rubber boot to close the gap where the water must be coming in.
Any suggestions, good idea, bad idea?

Thanks, Jes

Are you 100% certain that the leak is not coming from the zipper itself (teeth) and not the rubber stopper, per se? The reason I ask is that the end of the zipper near the rubber stopper gets a fair amount of wear. Obviously, if the zipper teeth are damaged, the only workable solution is to replace the entire zipper.

How many dives do you have on this particular dryzipper?

Not me. My TLS350 seals nicely. Wonder if there has been some sort of shrinkage or drying out of the rubber boot making it out of shape. Have you checked with DUI?

I have checked with DUI. They say to send the suit in to get fixed. I've already replaced the zipper once about 11 months of use. They put a new zipper in for free. The same thing happend then. The rubber boot stretches out and allows a slight trickle of water in. It is a design flaw. I'm just looking for a cheap way to repair it.

I have roughly 200 dives on the suit and 140-150 with the new zipper.

OK. Thanks for the info.
Drysuit manufacturers purchase the entire dryzipper (teeth, rubber stopper, etc.) from a third party company under the YKK umbrella (Dynat, BDM, etc.). This means that other brands of drysuits (not just DUI) are using the same kind of dryzippers. As far as I know, drysuit divers aren't complaining of this kind of failure.

You should be getting several hundred dives on a dryzipper. I wonder if DUI will replace the zipper for free under warranty.
