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. Review: Works Beautifully for its Intended Purpose - This is a specialty product designed to mitigate water, and corrosive damage for gaskets and other sensitive seals. I personally have used it to overhaul several aging coffee machines, such as my 1967 La Pavoni, and was amazed at the results at bringing my machine back to life. I also began using it on metal surfaces with contact rubber, such as the base for the classic Euorpiccolo models, as mentioned above and it has stopped any developed of rust in a traditionally vulnerable location. This product has numerous uses beyond what was mentioned and is well worth the money. ## Features - Valve Lubricant and Sealant - Container Size 5.3 Ounces - Temperature Range -40 to 400 Degrees Fahrenheit - Heavy Consistency, Grease Like Silicone Paste ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07VV6QZ7N | | Best Sellers Rank | #45,468 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #238 in Industrial Lubricants | | Brand | DOWBYTE | | Brand Name | DOWBYTE | | Container Type | Tube | | Customer Reviews | 4.8 out of 5 stars 188 Reviews | | Item Form | Paste | | Item Weight | 5.3 Ounces | | Liquid Volume | 2.02 Fluid Ounces | | Manufacturer | DOW Corning Chemical | | Material | Silicone | | Package Information | Tube | | Part Number | X476 | | Recommended Uses For Product | Lubricant | | SAE J300 Viscosity Grade | 16 | | Specific Uses For Product | Lubrication and sealing for espresso machines, grinders, valves, vacuum/pressure systems, outdoor meters, electrical system entrances, underground connections | | Unit Count | 5.3 Ounce | | Upper Temperature Rating | 400 Degrees Fahrenheit | ## Product Details - **Brand:** Molykote - **Item Weight:** 5.3 Ounces - **Liquid Volume:** 2.02 Fluid Ounces - **Material:** Silicone - **Package Information:** Tube ## Images ![Molykote DOW 111 Lubricant & Sealant, 5.3 oz.
