What Oring grease do you use?

[Natmart]

Just basic Trident is what I've used with success.

my impression is that Dow/Molykote 111 is not O2 safe.

Not safe for what, bvanant man, and realise a considered opinion Trumps an impression

 

[bvanant]

Well there is considered opinions and there is from the MSDS '"Can react with strong oxidizing agents." I would consider pure O2 at high pressure to be a strong oxidizing agent. The CCR guys say to use an oxygen compatible grease for HP bits but silicone is fine for low pressure bits. Personally, I use Tribolube for all my orings and stay as far away from HP pure O2 as possible except in our lab.

absolutely minimally oring only applying none to the grooves

I use even less than that. Too much attracts hair, grit, and dirt causing you to need even more. ChristoLube has been my go-to for a long, long time. Tribo-Lube is fine too.
