Lubricant for flashlight threads

I hear people talking about lubing? their new flashlights.

I have had a Solarforce L2i for over a year now.. but it ate the O-ring!

it didnt have sufficient (oil,grease whatever), and now its dry, and after opening and closing the
tailcap, its damaged, so I need to get a new o-ring.

BUT I would like to know where I can get some of that lubricant.. ?
Is this any good? from DX; Maintenance Lubricant for Bicycle & Flashlight (50ml)
I was watching DX. and someone says an Oring needs some silicone grease...
What do I need? lubricant, silicone grease?

please help me, would appreciate links to products, and explanation what to look for, what is good stuff, and what to stay away from..

Thanks

Are its threads anodized? If not, then avoid silicone grease.

I use mostly Bisley gun lubricant or deoxit red for flashlight threads and it works great. Greases tend to go everywhere and can be messy at times, so if you choose a grease do not use too much of it.

Now with 100% all natural asbestos!

I tried this:

but the threads felt gritty and the bare aluminium turned black in no time. Now I'm using this one:

Smooth threads and no mess to apply.

I bought some Nyogel some years ago. 

 

Now that SPAMBOT told not to use silicone based grease on Un-Anodized threads, I´m getting some ideas why my Solarforces make a constant & terrible mess...

Haven´t given a thought on it, really...

Good to know.. now I need to make things sure.. I guess my lights are a mix between anodized and not anodized..

what should I get then?

 

@agedbriar: what youre referring to from DX, is silicone grease, and SPAMBOT is saying to stay away from that.
Who`s right?

@SPAMBOT: what do you prefer (Please dont give me some brandnames from the US. Im in Japan, and would prefer stuff from internet, but rather some DX, DD, KD, MF etc, thank you)

Superlube I have been using it for over 20 years great stuff.

That's exactly what is happening with my blf tank e07. It was smooth and easy to turn before as it arrived lubed. Then when I use silicone grease (MF) it became gritty and black residue formed. I cleaned the grease off before continuing this post and the grittiness diminished considerably.

What is happening? Is silicone still advisable for anodized threads or silicone oil for all threads?

What exactly is the product name? Super lube oil? grease? Picture is fuzzy.

Engine oil.

 

I've used many things in the past, but this works fine for me. You can get a dropper bottle from DX with a very fine tip or a syringe type blunt needle. These are great for applying small amounts of oil to the right places.

 

If you want something thicker something like SAE90 gearbox oil ought to do the trick.

 

On badly worn threads, I use plumbers PTFE tape - as long as the negative contact isn't through the threads.

 

The numbers from my light tests are always to be found here.

Not sure which countries they are in besides the US, but the precision lube Radio Shack is some really good stuff for the price.  I was finding silicone gel too thick before I read about this stuff.

i use the liquid version of super lube. It works great! Anodized or not it makes the metal glide across pretty darn well and with just using one or two drops.

I've been using the DX silicone oil I linked to for several months on anodized and unanodized threads and I'm quite happy with it. Of course, I use it sparingly. Even so, I've learned to not touch the lubricated threads when I drop the battery in my hand.

Another lubricant that worked fine for me, although somewhat thicker, was a silicone grease that scuba divers use. My son pointed me to that one, as it's standard among divers, but I would have to drive to the city to buy it, whereas DX delivers to my doorstep. Smile

Nextorch "SL6" silicone grease, makes non-anodized threads "gritty" and produces grey/black crap that gets everywhere. Not recommended for bare threads. Works well for anodized threads tho...

Bare aluminum is inherently "dirty" so you are going to see some grey residue no matter what, your choice of lubricant can increase or reduce this however. Anodized threads are king since they are naturally much "cleaner". Deoxit is decent, does not produce "crap" nearly as fast as silicone oil and especially silicone grease.

Now with 100% all natural asbestos!

I thought petroleum based oil would damage the o-rings. It works okay for you Don?

I've used anything and everything ...having heard petroleum based oil isn't good for o-rings I opted for vegetable oil ,lip balm(bees wax) ,hand lotion,bear grease ,and finally silicone lube that I stumbled across in the garage . interesting to hear people don't  like it very much ..my feelings on it are mixed as well . Next i'm going to try machine oil like Don ..if my o-rings only last 12 years I'm ok with that too ..

I was under the impression that silicone got along with petroleum based stuff, I thought it was latex that had issues.

Sewing machine oil is another good lubricant, it works very well but it smells odd.

It would attack natural rubber O rings but should have no effect at all on silicone rubber rings. Most engine seals these days would be silicone rubber. Natural rubber is not cheap stuff, silicone rubbers are. It is possible that there could be some solvent effect with some lubricants and some O rings but I've never seen it. The only unwise lubricant I've used was heatsink goo (AKA cutting paste). Though I'd not recommend highly flammable ones or WD40.

 

I use the same bottle to oil the hinges of the horror film squeaky door just outside my office which gets opened hundreds of times a day as it leads to the wards.

Thinking that the o-ring was probably silicone anyway, I lubed the spindle of a top-leaking water tap with common petroleum grease, as that was the thickest I had and I didn't have a proper replacement o-ring on hand. The effect was that in a few days the o-ring swelled (natural rubber, evidently) and the leak stopped, but I don't expect it to last.

Ole WD40 isn't as flammable as it used to be.  It used to be a good starting fluid for small engines and propellant for potato guns until they changed the formula.

Still isn't a good lube (beyond short term) since it evaporates so quick.

This is my observation with my small collection of lights. Silicon grease works well generally for anodized threads & o-rings. Do not use it on bare aluminium though. Even without any lube/grease, black powdery particles can be seen with a simple finger wipe, that's how soft the alloy are. That's the gunk normally mentioned when silicone lube is used. There are reasons why at one end of the threads are not anodized and the reason chiefly being that its not meant to be open & close frequently, use the anodized end instead. If both ends of your light are anodized, its a big bonus and if both ends are not, there are other lubes that will work instead of silicone grease, SuperLube for instance.

I tried silicon grease. Now I use waterproof lubricant that came with a tap washer repair kit. Works fine. I have tried oil that is meant for lubing up fishing reels. It worked ok too.

I've used many products and they all seem to work fine. (all the different oils and lubes mentioned above however my ultimate favourite is paste wax (also known as generic furniture wax).  It helps provide a seal that is not greasy or sticky.  I wax it maybe once every 2 to 3 months.  Everytime I change out the battery I give it a quick buffing and it's back to new.

I've even used the those toilet wax rings on my torches once or twice before (although it's generally used to help me lubricate 3 inch screws to drive into wood).

good luck

Anti Seize Compound  $1.26 & free shipping from DrillSpot

Use just a TINY BIT. It will stain your clothes & hands if you get it on you, but it is electrically conductive, so joints like flashlight end caps & heads stay in good electrical (grounding) contact with the bodies.
