Curious what does “not compatible” mean.
Agreed except for personal preference but it’s not a silicone grease eh.
No grease is food safe except bacon. When a grease is labelled H1 it means it’s rated for incidental contact where less than 10 parts per million ends up in the food. More than 10ppm and it’s a recall.
And the ones that arent silicone, the ones that just say synthetic or multipurpose are petroleum derived.
It’s personal preference. It’s not a critical application. Use whatever you like to use. Try to avoid conductive grease and greases rated EP because they can be corrosive to copper and it’s alloys.
Edit: or graphite lube, it can be corrosive to aluminum.
Most important to remember, I think, is:
- We have no idea what our orings are made of. Theres a different ways to make a silicone oring and most of them aren’t even silicone.
- Orings are meant to be replaced. They won’t last forever no matter what you do. They degrade in air.
- It doesn’t really matter. It’s not a high stress or critical application. Use whatever you like to use. If it damages an o-ring you can buy 100 more for $1

Yes! My only complaint is that over time it get very gummy. I am talking a year or more though. But a quick cleaning and reapplication fixes that. This for the Synthetic Grease with Syncolon (PTFE).
Found it on Amazon UK, and there it says (quoting from its Product Description): “Plastic and rubber safe”, and “Suitable for all O-rings, seals, gaskets, portafilters, EPDM, Nitrile etc.” so should be safe to use on flashlights.
Additionaly, it’s rated 4.6/5 on 2142 reviews which is quite good. The 1-star reviews are mostly people complaining about the move from jar to tincan format, but this one gave me pause: “Hola amigos, no es grasa, es pomada. La grasa no se deshace y convierte en aceite y está lo hace, que es la función de una pomada… el que lo use en grifos beberá producto por tiempo… no lo recomiendo y el embalse pierde a si que ni siquiera se puede conservar bien, un auténtico engaño.” – in English: “Hi friends, it’s not grease, it’s ointment — grease does not degrade and change to oil, and this one does, this is an ointment’s function… he who uses it on a fawcet, will drink the product for a long time… I do not recommend it, and the container loses so much that one can’t even be well preserved, a true deception”.
Doesn’t sound too good, but perhaps it’s from someone who got a fake instead of the real thing? How’s your personal experience with it?
Multi purpose can be used on flashlights and door hinges.
The feeling is it gets diluted once applied. Leaves a film on threads instead of filling them. Although you apply it in solid state it kind of melts on thread and leave them looking wet.
It took some time before I’ve learnt how small amount is enough.
Referring to the downsides - it produces some moist only when stored in higher temperatures. Above 25 Celsius. But when you stir it the moist gets mixed with the lube again and offers its full advantages.
I’m not saying this is the best lube ever but for the fair price you can secure your needs for the rest of your (flashlights) life. And podobały for your next generations too

Will cause the o-ring to degrade over time.
De-Oxit Gold?
Petroleum jelly and mineral oil are highly compatible with Buna-N / Nitrile o-rings (which are the most common o-rings) and these lubricants are inexpensive and available in any grocery store. They are also not hazardous.
How do you know what material the orings are made of.
Overkill as hell, but since I already have it for another hobby (custom keyboards) and mainly stopped using it there in favor of another lubricant - Krytox GPL205. Compatible with all o-ring materials I’d know of, never breaks down, is food grade certified.
That popped into my head too, but I thought Grade 0 205 would be too thin to stay in the threads long term.
That and I didn’t want to use something that expensive lol.
(probably isn’t reliable but I think it’s a funny name)
I thought this was a joke until I clicked on it.

lmao. What a time to be alive.
Well, I took many of ya’ll’s advice and decided to try the Nyogel. I had just gotten a couple of new tubes of the Master Plumber Faucet Grease that I use, for $2.79 each, but I had jotted down the Ford number that had been posted above for the Nyogel equivalent. We have a Ford dealer a couple of blocks up the street, so I stopped in just to see if they had it in stock, and sure enough, they did.
It was an 85 gram tube for $24.74, and nothing smaller. I almost passed on it, but I figured what the heck, I’ll have enough grease to do a light the size of the space shuttle, so I grabbed it up since it was in stock. If I would have had to order it, I probably wouldn’t have.
I haven’t had the chance to try it yet, other than just feeling it with my finger and thumb. I will say, on the other light forum, there’s a long thread and many arguments about whether Krytox, Nano Oil, or Nyogel is the best … and a lot of talk about Nyogel turning black and becoming abrasive, yada yada yada. Well, my flashlight threads aren’t spinning at 8000 RPM for hours at a time, so I’m not too concerned about abrasion wearing them down. I mostly want smooth threads and to keep my O-rings from drying out. If I don’t like it, I’ll go back to the faucet grease, but I mainly wanted to try it on my Titanium lights, as we all know how ti threads feel.
Either way, I’m not too worried about it. I should have enough grease now to last for YEARS, and with many lights, for all the more often I have to take the cap of to charge the cell, I’m sure my threads will outlast me. Will update.

That’s actually REALLY small. That’s crazy small. About as small as they get. It’s super rare to get a specialty grease in something anywhere near that small. Pretty pricey, but it is a dealership so expected.
Put it this way, I was looking to order some of the exact grease used in one of my Milwaukee cordless tools I rebuilt a few weeks ago. The smallest size they sold was a 35lb bucket. It was iirc like $1,400.
It’s a common thing when you need a specialty grease for some reason to go hang out at a business that you know uses it and see if you can bribe somebody working there to give you a handful, because many are only sold in 55g drums

Well it’s 3 times larger than the 1 oz. tubes of faucet / valve grease that I’ve been using for a long time, and still have lots left … and way larger than those little tubes pictured above. It’s larger than a full sized tube of toothpaste. Based on the amounts needed for flashlights, it’s basically a lifetime supply. I definitely don’t have enough lights to use a 55 gal. drum, or a 35 lb. bucket, for $1400, LOL. We’re talking flashlights here, not Boeing jetliners.
Superlube is $10/3oz. I cant imagine one is alot better than the other or that your flashlights will last longer or perform better or have a higher resale value if you use one or the other.
