The Permatex 25223 is a black, formed-in-place elastomeric gasket maker engineered as a direct replacement for pre-cut gaskets. Its black formula is designed for higher oil resistance and greater flexibility compared to grey alternatives in the Permatex line. The cured material resists blowout and handles movement caused by vibration and thermal expansion. Temperature range runs from -75F to 450F (-59C to 232C) continuous, with intermittent capability to 500F (260C). The compound is sensor-safe and resists automatic transmission fluid, coolant, oil, and common shop fluids. Used on OEM production lines and specified in OEM service parts programs. Call us to confirm this is the right gasket maker for your application.
