Matan Posted April 28 Share Posted April 28 (edited) Hi eveyone. one of the o-rings on my Nauticam housing broke - can anyone share which size o-ring is required? Also - I'm assuming I'm doing something wrong here - any tips on how not to damage the o-rings of any ball mounts? Matan.

Chris Ross Posted April 28 Share Posted April 28 To clarify is this the main o-ring or the o-ring on one of the balls mounts? I've found the o-rings on the balls very durable my previous housing they lasted 6 years so far. Link to comment Share on other sites More sharing options...
Davide DB Posted April 28 Share Posted April 28 Ball mount oring code is 2-209 https://www.sealsonline.com/index.php?id_product=81454&controller=product&id_lang=1 Link to comment Share on other sites More sharing options...

I've found the o-rings on the balls very durable my previous housing they lasted 6 years so far. main o-ring break would flood the housing 🙂 it's the ball mounts - once of them just broke - this is a used housing so nothing new here, just wanted to make sure I'm not doing anything that damages them. I occasionally put some silicon grease on them as well. Matan. Link to comment Share on other sites More sharing options...
Chris Ross Posted April 28 Share Posted April 28 Yes I'm aware of flooding it could also break being installed. You need to be a little careful with o-rings and lubricant. The Nauticam o-rings are silicone I believe and if you apply actual silicone grease to them it can soften them. The Nauticam lube is a universal lube for o-rings, a generic silicone grease will damage the Nauticam o-rings. As I mentioned the Nauticam ones are very long lasting and I never did anything other than soak the whole housing after a dive, never added any type of lube. I don't believe the o-rings need lube as their function to grip. I recall someone mentioned the spec for the o-rings on here a while back but I don't remember the exact dimensions. Nauticam of course sell theirs but they are expensive. Link to comment Share on other sites More sharing options...
Matan Posted April 29 Author Share Posted April 29 Thanks, I'll just source new Nauticam ones and stop the lubing thingy. (yeah they are expensive but a one time payment for them every few years is still cheap - my CCR costs more annually 😄 ). Matan. Link to comment Share on other sites More sharing options...

Are you looking at the right o-rings? $16 USD for a pack of 10 (Backscatter, Bluewater Photo, etc) sounds like the cheapest purchase related to this hobby you might ever make 😛 1 Link to comment Share on other sites More sharing options...

I have never understood why manufacturers of various types of diving equipment continue to want to make money on o-rings. A set of o-rings from my previous rebreather from the manufacturer: 100 €. At the hardware store 10 €. 1 Link to comment Share on other sites More sharing options...

I just checked a few of my Nauticam arms (with balls) and my ULCS arms (with balls). I did find one Nauticam O-ring (on a ball) with a signifiant gouge in it - that one will likely eventually break. The ULCS O-rings feel a little more "robust" (defintiely less soft). A gouge could easily turn into a snapped )-ring given enough friction and movement.

Davide DB Posted April 30 Share Posted April 30 In my fifties I went from total black to black with some other color. I put it down to my midlife crisis 😉 3 Link to comment Share on other sites More sharing options...
bvanant Posted April 30 Share Posted April 30 2-209 o-rings in buna are like 10 cents and in silicone are like 25 cents. I like softer o-rings for positional stability and change them once a year (when I remember). The only exception to the size is the XIT 404 versions, they use a different size (and different sizes for different XIT balls bill 1 Link to comment Share on other sites More sharing options...
