ZeroHour Silicon Grease
Our flashlight grease is perfect for silicone o-rings and thread maintenance. We recommend keeping all your threads and o-rings clean and free from debris and to maintain its water-resistance features. This is a petroleum-based lubricant for silicone O-rings. Using silicone-based grease on silicone o-rings can cause it from over-drying.
