During the everyday operation when you switch the modes and tighten / loosen flashlight parts, O-rings and threads undergo friction and wear out. That is why special thread grease was developed to maintain top conditions of the flashlight and prolong its life. The best choice for use with flashlights is thick silicone O-ring grease (thread grease) Nyogel 760G. This thread grease is very sluggish and doesn’t dissolve in most liquids as water, methanol etc. Besides it reserves these characteristics in wide temperature range.

With daily use, especially in dusty or humid environments, as well as multiple tightening and loosening of the flashlight's parts (e.g. removing the batteries), the O-rings and threads are subject to friction and wear. NyoGel 760G is a high-quality polyalphaolefin-based grease that is essential for always keeping the flashlights with removable batteries in good condition. NyoGel 760G is easily applied in a durable and dense layer, it retains its properties in a wide range of temperatures, doesn't dry out and doesn't dissolve in most liquids.


  • Frost, thermo, moisture resistant grease (-40 °C..+135 °C)
  • Creates a dense layer that is impermeable to water
  • Extends life of the threads and sealing rings
  • Prevents oxidation and corrosion of contact surfaces, as well as fretting wear

It is recommended to clean the threads and O-rings of a flashlight and apply new grease once or twice a year, since the fouling as well as lack of grease cause fast wear-out of the threads and sealing rings. Remember that reliable protection from water and dust cannot be provided by worn-out sealing! In case of active operation and exploitation in dusty environments, it is recommended to clean and grease the parts as often as the necessity arises. It is also necessary to renew or add silicone grease before a planned submersion in water.

We recommend using Nyogel 760G when greasing Armytek flashlights' threads and O-rings.

The other reason to lubricate all threads and O-rings with silicon thread grease is its water-resistant characteristics. All Armytek flashlights are submersible up to 50 meters depth and can be used as lights for diving and spearfishing. Thread grease improves the water resistance of our flashlights and also enhances other features - eases mode switching and saves threads from wearing out. Flashlight grease can definitely prolong lifetime for threads in your device and provide you with better and most reliable performance.
