Review: Excellent lube for O-rings & plastic components - This is the lubricant you want to use on O-rings, plastic gears and such. It has so many uses that I have a tube in my basement shop and also one in my garage. It is expensive but goes a long way and is worth the cost. It is easy to work with and a good lubricant for many applications. One application that most people don't think about is on faucets. This lube is silicone based and is the required lube for O-rings and rubber seals. Put this stuff on the threads and you won't ever have an issue when taking the faucet apart to replace the seals, especially if you have hard water. I take my faucets apart about every six months and lube them with this Molykote to keep them working well. Molykote is a lubricant and seals out moisture. Use it on electrical connectors on vehicles and on bulb sockets. It is very tacky and prevents moisture from getting in and oxidizing the components.
Review: A must for any craftsman, mechanic, machinist or any other tradesman or hobbyist. - This grease and I have been partners for over 50 years. The name has changed a few times, but it is still the same great stuff. Short of high pressure axles and drive lines or the like, or high speed spindle bearings ,this stuff seals O-rings and other seals and preserves them for extended periods even under extreme use. Any motion on cylindrical, or square shafts will do nicely too. And, worn fan shafts will be restored to useful service with this grease. My first encounter was a freezer fan that was squalling and I cleaned it up , used this grease on the bushing and it lasted for years. It ability to work in higher and lower temps will also surprise you. Another use that was a godsend, was the O-ring seals in my Goldwing motorcycle air suspension. The rear suspension was always leaking down, new rings, same thing. I globbed some of this grease on them and reinstalled and never had an issue again. Ever have a ratchet drive wrench that is gritty or hard to use? Take it apart, clean it out and pack this on the teeth . Slick as heck for the rest of the life of the tool. You'll find many uses for this stuff especially for anything that you may assemble and disassemble multiple times. Threads never rust, rubber is nourished to retain it's elasticity, I could go on and on.

### ⭐⭐⭐⭐⭐ Best potable lubricant!
*by M***D on February 11, 2025*

Perfect lubricant for potable water situations. Used it on the o-rings and fittings for a pressure washer since the quick disconnect fittings were starting to become harder to insert or remove. Everything is operating smoothly now.
