How to lubricate O-rings.

[nutz_about_lights]

Hey all, one of the most common types of care that most CPFers have to do is lubricate the O-rings of the goods they unload their money on, aka flashlights. :nana:

Found this website (I've got no relation to it ) that gives a good write-up on the process and how to go about lubricating your o-rings. Also states that why we should not use alcohol to clean off old grease. Basically everything that has got to do with o-rings and lubricants. Worth taking a look IMO.

A few excepts:

''A lubricating-type grease is a viscous "gelled" material in which a liquid (oil) is usually suspended. Both the gel and its liquid are specially formulated to meet certain use requirements: temperature, separation...''

''And once the O-ring's surfaces are uniformly lubricated, any more grease you apply will neither improve the O-ring's sealability nor further reduce the coefficient of friction! ''

Hope you find the information useful.

I use Nyogel 760G.

I read the document, which turned out more interesting than I would have thought.

However, I'd ask: I thought you needed to lube uncoated aluminum threads also, to prevent galling.

I'm assuming this didn't get mentioned in the article as it was about high-end camera equipment (and so without uncoated threads).
