Let’s talk about something that’s been on my Amazon shopping list for a while – Super Lube O-ring silicone lubricant.
There are so many different types of oils, lubricants, and greases out there, covering so very many different applications and needs. This stuff is described as being dielectric, food grade, clean.
Basically, the dielectric part means it helps seal out and protect against moisture, the food-grade part means it should comply with NSF and USDA regulations governing use in certain equipment where incidental food or water contact might occur.
This Super Lube O-Ring lubricant is said to help with O-ring assembly, and as a lubricant. Lubricants typically help o-rings last longer and resist certain types of damage.
I added this to my Amazon shopping list some time ago, when I was looking for an easier-to-apply o-ring grease. I was mainly looking to buy this for flashlight maintenance, for o-ring lubrication and thread sealant.
I typically use Molykote 111 for water filter o-rings and general sealant applications, but it lacks an applicator and can be very messy to apply by finger. That’s why I am looking to get the Super Lube.
Super Lube also makes an o-ring silicone grease. My understanding is that this O-ring lubricant is a very thick oil, and that the grease is thicker – probably similar to Molykote 111. (The specific gravity, or relative density, is higher for the grease than the lubricant.)
Proper o-ring lubrication and seal maintenance can help prolong the life of products, but can be a mess to navigate. There are material compatibility concerns, proper oil vs. grease tackiness or weight ratings, and temperature considerations. For example, silicone oil and grease compounds are NOT compatible with silicone rubber materials, but are usually plastic-safe and work well with other types of rubber o-ring materials.
In other words, be sure to research material and application compatibility before you use this or any other lubricant or grease.
Price-wise, this O-ring lube costs more than say general-purpose Super Lube grease, but as it’s specially designed for o-rings and similar applications, it should perform better than a grease made for gears or similar.

This Super Lube O-ring silicone lubricant seems to be a highly recommended go-to, and I have had good experiences with some of their other products. Have you used this stuff before, or perhaps something similar?
