O-ring lubricant?

What should I put on the o-rings before putting a system together to keep them from drying out?

I usually use a silicon grease for normal applications, or Vaseline if I'm out of that (most o-rings these days aren't rubber), but will it get crud in the distilled water if I use it for a computer?

I suppose I could use distilled water, but some sort of oil/grease would probably be better if the system can handle it...

(I'm surprised no one's asked this yet...at least there weren't any topics found when I searched thread titles)

Thanks!

as far as i know it's no need for any lubricant on the orings

Okay...weird. Well, that answers that question

None needed.

O-ring lubricant... It's called K-Y... sorry I can't resist!

Wouldn't shoving a barb up there hurt?

Only if it's multi-ridged (or ribbed) barb. I know some stiff or tight parts do not like those at all.

We are talking about water hoses... right?

??? I hope you're talking about distilled for a lubricant and not "probably" for a loop? You should be using distilled water for the cooling fluid ...
