thanks, feel free to share links to products you like…
fwiw, I did use damping grease for the control rings on both a V11r and an RRT-01, it does not leak out:
“NyoGel 767a Damping Grease stays where it is put, making it the preferred lubricant for sight scopes, telescopes, microscopes…”
another product Ive read good things about for control rings is
Krytox 205 which is supposed to be particularly good for Titanium. I have not tried it yet.
Another product I have heard good things about but not tried is Tef Gel, but some of my googles refer to it as antyseize and a substitute for locktite, which confused me…
I have also used darksucks munky spunk for titanium threads, but that is a different application than control rings… and I have used Nano Oil, which again is for threads, not control rings, which as you said requires thicker stuff, that is referred to as “damping grease”.
Here is a thread that helped me learn about other products as well
[QUOTE=Tekno_Cowboy;3088346]
Something to note: When using PTFE (teflon) or silicone lubes, the quality can vary greatly dependent on the quality of the thickener used, and the quality of the base oil. One can work very well, while another of the same type can perform horribly.
O-Ring Compatibility
Use caution when using petroleum products, as they can damage some types of o-rings.
Don’t use silicone lubes on silicone o-rings. The o-rings can swell and make your light almost impossible to get open.
Very Good Lubes
Nyogel: This lube is used by Surefire. This lube tends to change color slightly, but that should not affect it’s lubrication properties. 759G/760G is tuned more for threads, 779ZC is tuned more for o-rings. Nyogel 767a is a damping grease, good for control rings on RRT-01 and other magnetic rotaries.
Super-Lube: A cost-effective teflon-based lube that provides very smooth action. Both the grease and the oil perform well. It can be purchased from many hardware stores and online retailers.
NO-OX-ID: A wax-based lube with excellent anti-oxidation properties. It’s been around for about 50 years.
Krytox: One of the best lubes out there. This is a fluorinated grease that is very non-reactive and is safe for just about any application. This lube works exceptionally well on Ti lights. It is available in many different varieties, and has several re-branded names. It has been discovered that the sodium nitrate additive in the anti-oxidation varieties of Krytox can reduce the wear-resistance of Krytox on Ti and bare Al. The difference is small, but it is something to make a note of. It can be purchased from Amazon or directly from a DuPont distributor.
Krytox Variations and Re-Brands:
Finish Line Extreme Flouro
Loctite PFPE Grease
Chris Reeve Knifes Flourinated Grease
Sandwich Shoppe 50/50 mix
Nano-Oil: A highly-recommended lube by forum members. The lube uses oil as a carrier for nano-particles that are designed to act as a bearing surface. Also comes in a grease.
Good Lubes
Pure Silicone grease: This is a very common lube that can be found just about anywhere. It is generally safe for use, with the only exception being use on silicone o-rings.
Tri-Flow Clear Synthetic Grease: Similar to Super Lube. Will be moved to the Very Good section if there are more positive responses.
Deoxit ProGold: Anti-Oxidation electrical contact conditioner. While not a lube, it can be a good addition to electrical contact points on lights.
Poor Lubes
Motor Oil: It may work, but it can damage o-rings. A full synthetic like AMSOil might be safe, but why take the chance when there are better lubes out there.
Petroleum Jelly/Vaseline: Contains petroleum distillates, which can damage some types of o-rings.
Moly Grease: While very useful for other applications, Molybdenum is toxic, and should not be used for handheld applications, such as flashlights.
Lithium Grease: Contains petroleum distillates, which can damage some types of o-rings.
Bad Lubes
WD-40: It is a solvent, not a lube. It actually increases friction on the threads.
Other Lubes
Loctite ViperLube
FrogLube CLP
Militec-1
