Chafing drysuit neck seal

Three days of diving in the ocean and my neck looks like this thanks to chafing from my drysuit latex neck seal. I don't have this problem in fresh water. I can be diving quite happily in a fresh water cave system, then slip down through a halocline into salt water and rapidly feel the chafing begin (I don't get wet inside my drysuit so the neck seal isn't leaking). I've had this problem to varying degrees over the last couple of years. Some neck seals it's not an issue, my current seal is the worst I've encountered (I'm getting about 6-8 months out of a neck seal as I'm diving quite a bit). Does anyone have any idea why this happens, or how to prevent it?

my wife had the same issue with her Otter suit, we did 5 days last summer with 3-5 dives a day. It looked like huge hickies! :lol: She found vaseline the best thing. Pretty sure that wont be do too much good to the seals though. She reckons if you are done diving for a bit (a week maybe) then BioOil has some pretty good qualities. again not sure what this will do to the seals.

The other thing to consider is next time you replace the seal get silicone ones instead, they tend to be hypo-allergenic, actually form a better seal and are much kinder to skin. My wife has done research using a silicon based dressing for the prevention of skin damage from radiation treatment. Its amazing stuff!

...and yes, she is the brains of the outfit :lol: :lol: :lol:

I understand petroleum products have the ability to break down latex so that rules out Vaseline. I don't need to be replacing my neck seal more often than I am!

Unfortunately I don't think I can currently get silicone neck seals done in Mexico.

But thanks for the suggestions.

You can get short and very thin neoprene sleeves for your neck that prevent this. They work brilliantly. I can't find a source right now but will let you know.

This is probably what I have seen used. They are great by most accounts.

Now that you remind me I remember Kaz using something for her neck. Does anyone have an email address for her, and can PM it to me?

Unfortunately it does say this in the product description:

This product does contain oils which can cause early wear in latex type seals.

Well from what I have heard the early wear warning is oversold. Seems an ok tradeoff to me. But Kaz will have a much better idea.

I used to use 'priceless' silicon spray (comes in blue aerosol), to lube my seals on the drysuit, at keep them from premature splitting.
Some of the silicon sprays have a alcohol based propellant, which is not good for the seals (or the neoprene).
one of the guys I played underwater hockey with used to carry a tub of o-ring silicon for using on his mask for a similar reason.

I cant think of anything more relaxing, than being in the downunder, breathing some nice clean fresh filtered 21% nitrox.

Hi Ali,
I would not use anything near the seal in an aerosol, silicone or petroleum based as they will all speed up the decay of the seal. The Bio seal option is a good one or change out to the silicone seal system and then you can replace them yourself, given the amount of diving you are doing it would be well worth it. Cheers ant.
