Permatex Optimum Black offers a unique combination of maximum oil resistance and flexibility. With the evolution of components and materials, such as plastic/steel and aluminum/steel, each with different rates of expansion and contraction, it is essential to have a reliable product that can adapt to these changes. Furthermore, as technology progresses and regulations become more stringent, there is a trend towards thinner metals, fewer fasteners, and wider bolt patterns.

Optimum Black is specifically designed to handle the added stresses and changes that come with today's lightweight, high-performance, and premium component assemblies. This advanced RTV silicone gasket maker is sensor safe, low odor, and non-corrosive, making it suitable for a variety of automotive applications. It meets the performance specifications of OE silicone gaskets and is resistant to both automotive and shop fluids, as well as vibrations. Additionally, it is 15% stronger than the popular Ultra Black product.

One of the key features of Optimum Black is its patented adhesion system, which allows it to retain the highest level of flexibility while offering maximum oil resistance. In fact, it is 60% more flexible than Ultra Black, ensuring durability and reliability in a wide range of temperatures. Its temperature range of -65 DegreeF to 500 DegreeF (-54 DegreeC to 260 DegreeC) for intermittent use further demonstrates its versatility and suitability for various operating conditions.
