I recently purchased a Zen dp-100-NT port second hand to use on my Nauticam housing. It came with a Sea&Sea blue o-ring, but no silicone. Is it safe to use Nauticam silicone on the o-ring or does it need to be Sea&Sea silicone?
As my housing is coming in from maintenance today, I'd really love to take the Zen for a dive tomorrow, but I am scared of using he wrong grease and possibly causing a flood.
Anyone with experience on this?
