Is that silicone/compound any good?
 

Got this for cheap and before using it i want to make sure it's good. It says it's good for rubber and plastic o-rings.
Thanks

What were you planing to use it on? It's going to be too thick to use on a GBB, so if you're using it for your mechbox gears I'd assume it's ok, as long as it DOES NOT CONTAIN PETROLEUM DISTILLATES.

That stuff was invented in 1943 for keeping moisture out of airplanes!!! It's not intended as a lubricant but will work okay as one, it's for electrical insulation from moisture.

Dimethyl silicone compounds should not be applied to O rings or other components made of silicone rubber because they will destroy the silicone rubber. These compounds will also slightly swell natural butyl rubbers.

It won't work for lubricating your piston head o-rings, your GBB mags, or valves, or anything like that. Put it on gears and only gears.

...or don't be a cheapass and get some proper lithium grease.

Got it for free and it's a $15us tube. Don't worry about me being a cheapass, i just ask, what is a forum for if it's not to communicate. ;)
Thanks to the others

Well, whatever works. Personally I prefer to be safe and just get the proper stuff from the beginning.

I didn't say i was using it, thats why i asked before to peoples who knows best like you. And thats why i will keep this grease for my car or tools.

I'm pretty sure the O-rings aren't plastic. That's probably something you'd use on a circuit board or some other electrical application.

I probably wouldn't use it for gears either. Stick to the "tried and true".

That being said there's nothing preventing you from getting a comparable O-ring from a hardware store and testing your stuff on that.

The Tube you have in the picture was made for electrical wiring. Mainly an anti-oxident to prevent the natural wear and corrosion of materials carrying, conducting or are in contact with electricity. Back in the day when electrical wire was aluminum instead of copper you would add this when joining the two diferent materials together to prevent the copper from corroding. You would also use is when fastening any two different types of metals together to pervent corrosion.
Metal is like women they have a hard time getting along with one another. Just kidding ladies.
As for the plastic and rubber o rings again with electrical Marretts or marrs or the cap shaped wire connectors which you twist on to attatch two wires together uesd to have plastic or rubber o rings inside to hold the part of the connector that holds the wires together as does some types of automotive fasteners.
You may want to put some on a piece of paper and let it sit for a few days to see how it reacts. It may be old and harden. Some also acted as a glue drying like Caulking would while others could be used as a lube.
I would hate to hear your gears are all gummed up
