OPTIMUM BLACK® Gasket Maker

Description
Permatex OPTIMUM BLACK® RTV silicone gasket maker combines maximum oil resistance with high flexibility. The trend is towards increasing use of dissimilar materials (plastic/steel, aluminum/steel, etc.), all which have different rates of expansion and contraction. In addition, with technology advancing, regulations and requirements tightening, designs include thinner metals, fewer fasteners, and wider spread bolt patterns.

The strength and flexibility of OPTIMUM BLACK® is designed to handle the changes and added stresses that exist between today’s lightweight, high performance, and premium component assemblies. It is sensor safe, low odor, and non-corrosive with resistance to oil, shop fluids, and vibration.
