What is a good lubricant to use on rubber, like hoses and o-rings? Will grease deteriorate the rubber? Is a cream soap acceptable? Is vaseline best?
Thanks,

Are you sure it's talcum powder, and not sodium stearate? Rubber has white powder on it from the sodium stearate used in manufacturing (release agent?). I don't see how talc can prolong the life of rubber.quote:

I use Dow Corning MolyKote 55M grease. It is a Silicone O-Ring lubricant and meets MIL-G-4343B. This stuff is very oxidation resistant and is very effective for dynamic lubrication between organic O-rings and metal parts in pneumatic systems. I use this stuff on all my hose installations and any O-ring or gasket. I have had one 5.3 oz tube for as long as I can remember.quote:

The white powder that you see on some rubber parts is used as a means of keeping the rubber parts from sticking together after the manufacturing process. A silicone lubricant is the best thing to use for lubrication of rubber parts.quote:
