curious why tribo 66 is not recommended for closed circuit rebreathers. what is the reason for this? i know tribo 71 is recommended for both closed and open.

thanks!
 
From another forum:

Tribolube 66 would be a replacement for the ChristoLube mcg129.

Tribolube 71 is for static and dynamic applications. This grease is PFPE oil thickened with PTFE has a lighter viscosity and a wider operating range. The grease is based on a linear chemistry. Tribolube 66 is only for static applications. This grease is also PFPE oil that is thickened with PFPE, but has a thicker viscosity. The grease will thicken and in cold conditions can cause a sluggish response, due to the fact that its operating range is not as wide. This grease is based on a branched chemistry.

So tribolube 66 would be good for things like the shadowmount fittings ISC makes, etc.
