FJ23 FracJack Graphite is a premium, general-purpose, high temperature graphite grease. Formulated for frac applications, FJ23 protects threads and provides sealing over a wide range of temperatures. It is especially suitable for moderate loads and speeds at normal or high temperature service. FJ23 is compounded with graphite for added residual lubricity and extreme pressure properties. An application of FJ23 provides a lubricating film that prevents friction caused by metal-to-metal contact thereby extending the life of the frac valve. FJ23 contains no metals making it ideal for applications where make-up torque does not require the presence of a metallic compound. It is water-resistant and contains additives for added protection against rust and corrosion. FJ23 has excellent mechanical stability and retains its consistency under high temperatures.
