We successfully used LOX-8 grease
<https://www.fluoramics.com/fluoramics/lox-8-grease/> for ball valves
modified for LOX.
It would be interesting to hear about other options though.

What are the different options for lubricants to use for valves that carry
cryogenic fluids (liquid oxygen/methane).
I searched online and can't seem to find one that can work well below -112
degree celsius.
Since Liquid oxygen is -183 and liquid nitrogen -210 there must be some
sort of lubricant that is used in valves that operate with cryo fluids.
