Lesson 4: Optimum Grey

Permatex Optimum Grey combines maximum vibration resistance with maximum torque load. Today, we see components changing and unlike materials meeting (plastic/steel, aluminum/steel, etc.), all with different rates of expansion and contraction. In addition, with technology advancing, regulations and requirements tightening, we see thinner metals, fewer fasteners, and wider spread bolt patterns. The strength and vibration resistance of Optimum Grey handles the changes and added stresses that exist between today’s lightweight, high performance, and premium component assemblies. Optimum Grey is sensor safe, low odor, and non-corrosive with resistance to oil, shop fluids. It is one of the most advanced, maximum torque, maximum vibration resistant RTV silicone gasket makers available.
