It's not a huge deal but I think there might be something better than silicone . . . or, maybe I could just keep it off the threads?

Hey Foy. What's your problem with sil grease? I use it over a year now and found it to be perfect for threads and o-rings. Even Solarforce uses it on their flashlights. ;-)
They make non-anodized threads gritty. Black small particles will appear after some time.
my Quark has non-anodized threads and there is lots of black small particles. i thought it was aluminum.. but aluminum is silver, not black.
eventually i found out that it's rubber from the o-rings. lots of it.
i cant find any of the suggested synthetic lube stuff over here at my place (amazon shipping costs, no way). If Vectrex, who lives in G. too, uses nextorch sil grease on his torches, then i can do it too!
haha.
EDIT: i guess nobody knows a flashlight lube product on Dinodirect?? have some dinopoints left..
same xD
I too don' like the nextorch grease on not anodized threads... and is also hard to apply(very dense, I use a silicone brush used in optics) and come in a very small quantity with a lot of wrap..
Is there any website that ships Super Lube internationally at decent prices? Amazon wants to charge me close to $100 for shipping alone!
I tried stuff like nyo gel before and absolutely hated that stuff, it's like a very thin oil and goes all over the place. I had it on the battery, in the tailcap and even on my clothes. What I like in silicone based greases: that it stays in place if you apply it right (very thin film layer ... best use a Q-tip to apply), that it is colorless ... opposed to many mineral based oils, that it treats O-rings (which are also silicone mostly) right and that it is non-toxic for humans. So if you eating a sandwich while lubing your flashlight or accidentally tap on the threads during battery change... no biggie.. you won't poison yourself. Scuba divers trust their lives by this stuff... being unable to breath is very unhealthy. It's no coincidence that nextorch and many flashlight manufactures choose silicone based grease when they ship their lights. There might be products that do one or two aspects better than sil... but the whole attribute package is hard to beat... especially in the budget sector. I personally ordered original scuba dive grease off ebay, but only because nextorch wasn't available back then. A friend ordered the nextorch stuff and he seems pretty happy with it. The fastest way to get sil in Germany is to buy stuff for expensive coffee makers or scuba supply but I don't like the packaging. Scuba supplies are often 60 grams and more... way too much and the coffee supplies are in those tubes which get in the way of applying the sil thinly and the tubes often only contains 6 g... so too expensive.
Well I found one that will help some of you: Midway USA
They advertise this as a gun grease, but it's the same product. If you scroll down to the bottom of the page, click on Shipping & Return and a pop up menu will appear, scroll down to near bottom and a list of European distributors appears. I checked a couple, but they are not in my native tongue. However, they all carry some manner of grease used for guns, which I have seen as a good substitute for flashlights according to many posts on the subject.
For others, I found a US seller that ships Super Lube overseas: Illumination Gear
(Also a new flashlight source for me!) Prices are reasonable and they offer flat rate USPS international shipping. Just click on the 'International Shipping' on the left menu.
The EagleTac costs 2.50EUR .. nice price!
Btw, the Jetbeam product is said to be compatible with ALL flashlight brands!!!
The Jetbeam and Nitecore are pretty cheap at IOS. Especially if they are ordered with other products or 3pcs.

You mean that my Xeno won't explode if I use jetbeam sil on it? Phew, that is good to know.... ;-)
syl-glide is what i use
i think i bought it @ a car parts place. says rite on tube "harmless to rubber"
waterproof, extreme temp tolerance, non runny
My own experience exactly (speaking of NexTorch grease, aren't we?).
DX silicone oil is smooth. Threads remain clean much longer. Alternatively, scuba light silicone grease.
EDIT: Seems available...?
Yes, Nextorch silicone grease on non-anodized threads. Otherwise they work fine.
I wonder if Nextorch is any different in composition than any other sil grease out there? I have to compare it to mine next time I have access to it. Is the grittiness just cosmetic, or does it shorten the lifespan of the threads? Does someone have a pic or something, that I can get a better idea of the effect?
What grittiness.. i thought you like it for what it's worth. Does it mean that cheapo me has to cancel the DX order? :D
leelou, foy, agedbriar reported problems on non-anodized threads (specifically with NT grease) .... I use scuba sil, a friend told me that he uses nextorch and is happy with it... I assumed that silicone grease is silicone grease no matter what brand... apparently mileage varies a little. If sil grease would be bad in general for threads.. I'm sure the top brands you listed wouldn't use it... so the question is: Is especially NT sil substandard or not, or did they change their recipe.
yeah, the top brands use it because theirs are anodized threads. i wont cancel my DX order. i dont own more than 10 little torches and the threads are all anodized except for 1 brand. o-rings are all rubber which is the standard, and the NT sil will perform fine on them.
i would have bought the recommended superlube but i wasnt willing to pay the disproportionate shipping costs. In the U.S., superlube is a budgeteer's choice (it's so cheap maybe because it's produced in mass quantities and available in every hardware store); and since i am spoiled by the Ch*nese No-Shipping-Costs-philosophy or policy (also seen on ebay often), superlube is a nogoh.
With a positive attitude i am sure not to regret the ultracheap NT cr*p. haha. (2.60$ total)
jo guys, FYI. i know that others on THIS and on other forums and in many threads repeatedly warned about silicone grease. but some people may rather want to see it by themselves in person (like me the el cheapo and el budgee) or hear it from people they know/trust (like the suspicious kreisler me? hehe), so i am repeating it FOR EVERYBODY TO HEAR IT AGAIN:
Nextorch Silicone Grease is highly NOT RECOMMENDABLE, and i promise that you will regret the purchase if you apply it on all kinds of flashlight threads. And here is the most obvious reason why:
check out this video first:
Have you seen the part with the tooth stick? Dont you think that this is weird? It is!! It demonstrates the most essential (positive/negative/youdecide) physical property of silicone grease:
IT IS EXTREMELY STICKY.
With "sticky" i dont mean the stickiness of sugary stuff like dried Coca-Cola or syrup (which is disgusting. i never drink soft drinks. because they make my tongue sticky haha), or the stickiness of glue stuff like glue, scotch tape, etc.
With "sticky" i mean the stickiness of tooth paste or any other (non-oily) highly viscous matter. Grease and tooth paste are still called "fluids" although they dont flow or pour like real fluids (oil, syrup, water, beer).
So tooth paste will "stick" to anything solid, any solid surface it comes in mere contact with. And if it is a layer between two (moving or not) solid surfaces, then it sticks to both. And silicone grease behaves even more like tooth paste, to an extreme degree as showcased in the video. So what *is* the definition of "lube"? Is lube defined as any fluid which is applied between moving parts, or does the fluid have to have a certain set of physical properties to be called "lube" after its definition?
Here is what silicone grease obviously does due to its extreme viscosity:
And here is what silicone grease DEFINITELY does NOT do. The downsides of silicone grease:
The above blah treated the physical properties of silicone grease on threads. On o-rings it does the best sealing job and it's better than using dry o-rings. But here again "smoothness" in the sense of "easy twisting action" is something different. Silicone grease on o-rings is *not recommendable at all* if you want easy twisting action, e.g. on the twist UI of AAA lights or the 8-mode UI of the Quark Tactical. While the grease spares o-rings (because dry o-rings flake or show signs of abrasion), it does NOT provide easy twisting operation on the o-rings (nor in any threads!).
What about the chemical properties (interactions) of silicone grease on threads (aluminum, stainless steel, titanium) and on o-rings (silicone o-rings, rubber o-rings)?
i dont know. I mean who cares. The above listed physical properties suffice to declare silicone grease as crap for flashlights. It's only good for sealing purposes (Xeno E03) or for reducing the wobbliness of loose threads (2 threads of the Romisen).
**ck it. really.
Thanks, kreisler - very informative. I haven't tried the Nextorch grease but my first attempt at lubing was with some Silicon dielectric grease and I was not impressed. I'm really starting to like my bike chain oil - the key is very light application. Might stop by a Gander Mountain store and see how much gun lube costs just to try it out.
