Can white lithium grease used on O rings?
Simply so, is white lithium grease safe for O rings?
The grease is slick and harmless to o-rings and the teflon matters where there's metal to metal contact (the threads of our lights). This grease is the type recommended by Surefire in that it's non-migrating and won't flow where it's not wanted due to heat within our lights and make a mess of things.
Moreover, what is the best lubricant for O rings?
Why silicone lubricant grease is the best type for rubber o-rings and seals. Most O-rings are made from synthetic rubbers. Namely: nitrile, EPDM and Neoprene. It is true that petroleum products will degrade natural rubber.
The word dielectric simply means non-conducting which is nearly synonymous with the word insulator, meaning it does not allow the flow of electrical current. White lithium grease is a multi-purpose grease used for gears on all locomotives, including those with motor worm gears.
