I have read and read and read. Quick question, can I use krytox 50/50 on all my lights? I have a Mcgizmo PD and read krytox was about the best thing to use for it. I also have a Surefire A2 and read Nygel 760 was the best thing to use for Surefires.I don't want to buy a different lube for every light, but if I have to I will. I was hoping I could buy one to take care of both the threads and O rings on each light. I know it's been asked a thousand time. Any help would be great.
 
I use Nyogel on all my lights, stays clear and doesent get grey like the silicone grease I used to put on my babies...my 2cents
 
So nyogel for the pd also? I just want to make sure to use the right stuff!
 
To answer the original question, yes, Krytox 50/50 is safe to use in most lights for both o-rings and threads.

I've tried pure silicone grease, PTFE grease, several of the Nyogels, Magnalube, and Krytox 50/50. I prefer Magnalube in many of my lights for it's ability to stay put under high heat conditions, but I prefer Krytox for silky-smooth operation. If Krytox 50/50 wasn't so expensive, I'd probably use it on all of lights, except my hotwires. But those are my preferences, and we all have our own. There isn't a "best lube", just better suited ones for particular situations.

As long as you use a lube that takes into account the materials it will be used on and whether electrical conductivity is needed, you'll be fine with whatever you choose.

Point of interest, guys: No lubricant is conductive.
Other than graphite or metal-filled pastes, all are high-dielectric insulators.

Oil is a an insulator. That's why big transformers are filled with oil. Ignition coils (old ones) too.

Silicones are insulators too.

So, how can non-conductive lubricants allow our flashlights to even work?

Simple: the metals still make contact through the film.

Greased or oiled electrical junctions are "a good thing" for general electrical work. By sealing off the metal from corrosive elements, the metal stays cleaner for much longer. As long as there's a wiping or a pressure contact, contact will establish through a grease or oil film.

So, no worries.
 
I don't have any dedicated flashlight lubes, but I have knife lubes. Can I use Miltec or Tuff Glide on flashlight threads?
 
First, start by asking your partner. Her preferences and comfort level with the whole lubing process is important for long-term relationship stability.

Oh, I'm in the wrong forum? I thought this was CandleLightForeplay.

My Fenix L2D started acting weirdly. Turn the "on" button and it waits for about a second, then cuts on.

Or else hit the on button and nothing. Have to click it on and off repeatedly to get it work.

I figured dirty threads. cleaned them with alcohol, then lubed them with synthetic brake grease. I am sure there are better products but it's all I had on hand. Seems to work well now.
