RO/DI O ring lube

[hillegom]

You know, I misread the original post.
I do not use any lubrication except water when I put a new membrane in.
I lubricate the big O ring that seals the canister when I put in a new cartridge of carbon or particle filter. I find that helps to undo the canister next time

thanks guys for your inputs. the unit is fairly new, so no need to lube it.

dang! too much 'you_tube'
