BOV - Which Lube?

Dive!Dive! · 16th January 2012, 11:22

Been using good old chrystolube on my Golem BOV for a while, but feel its not ideal as it gets sticky after a while, then hard to turn.
Any recomendations for something better ?
Thanks

I use silicone grease and it works just fine. There is no pressure in the BOV high enough that you have to use an O 2 comparable grease

Wesson cooking oil works if your in a bind.

Tribolube is very good, it doesn't seem to "cake" and get tacky like the Christolube does and is also O2 safe.

Tribolube 71 is what you're after, I noticed a significant decrease in BOV turning effort after using this stuff.

+1 agreed!

I have used O2 lubricants from Christolube, Krytox and Trident but in my opinion Tribolube is the best. It's true that silicone grease can be used with ambient pressure parts of the Rebreather system but to prevent cross contamination it's better to just stick with one O2 lubricant and I recommend Tribolube.

Silicone grease too...

Since I never really followed why someone wants to use expensive oxygen lube on LP areas mitigating the at such pressures low oxygen fire risk with far lesser lubrication performance..
I absolutetly do not get why someone would do it at ambient pressure connections (as the barrel on a BOV for switching OC to CC and vice versa or covoluted hose Orings, or DSV Orings)...

Use Silicone grease and be happy.. Some vote for food grade quality silicone here.. but also here personally I do not really have concerns..

As always though.. it is up to you!

Now that sounds quite academical to me rather than from a practical point of view..
Given a due dilligence when maintaining your equipment could you give a real life example how such "crosscontamination" creating danger (so I am speaking getting somehow into an HP area) supposedly should happen?

Not saying it should be done one way or another but I have had both my silicone and my o2 lube come open or get punctured in my tool bag and or spare parts kit making me have to clean some parts before I could use them. So I know lots of people who avoid the silicone so they don't accidentally grab the wrong one when using it on a HP area. Or accidentally grab a HP part that has had silicone dripped on it. This being said any HP parts technically shouldn't be handled without gloves and most people do when changing out a hose, putting in a HP port plug etc.
It depends on how careful you want to be I guess.
