I've used it for a very long time. Only times I've had issues with it was when I had lights in VERY cold weather. The threads get a little stickier unless you keep it in a warm pocket or until the light warms up from use.. How much are you putting on the threads? Clean the threads first as well.. with a toothpick or something. You don't need to use very much 760G.

I find use of all the toothbrushes I get from my hygienist work great for cleaning threads.
US Army boot camp also taught me how to clean toilets with my personal toothbrush. They knew i was good for something!
I just run a toothpick through it normally. Then wipe the threads off with a napkin. I don't think it needs to be more complicated.

I like Nyogel 760g very much.. It even works on Titanium threads. And, it glows under UV, so I can check if I used enough.
To clean the threads I use isopropyl on a paper towel.

I used it very sparingly. In fact it is so thick it barely comes out of the small pin hole on the tube. It is so thick it feels like it drags when screwing on the head or tail cap. I was expecting something more like like die electric or silicone grease. A surefire rep said they use Nyogel but it is the 779ZC & 759G.
"For orings we use Nye, Nyogel 799zc which is a thick nonconductive, nonmigrating grease that will not cause the orings to swell and thus break or shear.
For threads we use Nye, Nyogel 759g which is a nonconductive grease that works well in aluminum to aluminum applications.
NOTE*** even though the grease in "nonconductive" it is not an insulator either, The 759g is used on connectors mostly.
Posting these descriptions is okay.

That is interesting, which infers that SF uses 2 different products for O-rings and threads at the same area. This doesn't seem very logical, I would think the 2 products would immediately mix when screwed in place and used.
So much for the old saw that SF used 760G. I use it, because that's what "everyone" said SF used years ago and my big tube from Lighthound will outlive me. Works fine for me, maybe I'm not so picky. I like that it's clear.

That is not my experience.. maybe try without the battery installed.. to eliminate drag from that source.. I dont get any drag, just nice smooth operation.
FWIW, Oveready uses Nyogel 760a on all the lights they sell, not just aluminium, they also use it on their Titanium lights..
as far as the Oring comment from surefire, I agree
Silicone is not compatible with Silicone O rings, but thats not what our lights come with, and thanks to louie, I just learned Nyogel is ot Silicone it is PAO.
"NyoGel 760G is very similar to 759G. In fact, NyoGel 759G is now replaced by NyoGel 760G. NyoGel 760G offers slightly higher thermal stability and is rated for temperature ranging from -40°C to 135°C. In addition to that, NyoGel 760G has UV dye for inspection and copper passivator is added to it for enhanced corrosion prevention."
I dont read it that way. My interpretation is that the two products are used interchangeably. which tells me that lots of different
they are all
regarding the term Silicone, though not correct for 760G, there is at least one seller on Amazon who describs his Nyogel 760G as Silicone
Thanks to louie for finding the PAO info..

You and me Louie.. it's all too dang technical!
Ah, it looks like OP is reading a 2002 thread about these greases. I saved an old review (2008) on these Nye greases from the old "CPF Reviews.com" site. It looks like 759G is no longer made and replaced by 760G, which is nearly the same. I can't find info on 779ZC (or 799ZC) on a quick search on Nye except for some MSDS sheets, but another Nye document I have says 779 is a very light action general purpose damping grease. 779ZC is described in the review as much thicker than 759/760, and suggested for thicker threads.
OP may want to look for a thinner grease if unhappy with 760G.
What I recall is that 760G is widely used by auto manufacturers to stuff their electrical connectors with. And it does not seem to affect silicone O-rings, which I saw with some silicone (red) rings I got from the Shoppe and IIRC, Superlube grease.
I also keep a tube of Nye 767A damping grease, which gives a medium drag effect which I find great for things like Sunwayman control rings.
(edit: corrected reference to "750G" to 759G)

The large tube of 760g I have is relabeled Mopar. Sells for half the price of Nyogel branding.
Hey, it's all silicone grease however it's labled..

Actually not, these Nyes aren't silicone. I also have a tube of Ford/Motorcraft rebranded 760G. At least that makes it easily available and affordable. The weird stuff like 767A isn't.
I read that page too. Its doesn't feel gritty or anything. Its smooth but just seems stiffer.

thanks for that link, very helpful.. so 760G is made from synthetic PAO not synthetic Silicone..
synthetic good.. ;-)
Nyogel good.. lol
ah, yes, I think I understand what you mean
it is a damping grease, the silica does slow down how fast the threads rotate..
And as louie said, the 767a is even more heavily damping, which is good for Sunwayman and Jetbeam Rotary dials.. makes them smooth, but also slow..
Another lube alternative, if you prefer a drying oil, over a grease, is Nano Oil, it works very well for O rings, but has essentially no gap filling properties. 760G has a lot more gap filling properties, which is why I like it for threads..

I've been using my same Nyogel 760 tube for a couple decades. It's fine for me. I like the thickness. After applying I make sure it is evenly spread out. Can move it around with your finger then thread the head or tail cap on and off a couple times.
I ordered a tube of this stuff yesterday. For clock movements I sometimes like to apply oil & grease with small glas syringes with long needles to get into tight spaces. Id think this would work for this grease as well. But yea, a toothpick is probably sufficient..
