Permatex� premier instant gasket maker was designed as a replacement for conventional gaskets. This elastomeric �formed-in-place� material is more reliable and longer lasting than pre-cut gaskets. It is blowout resistant and protects against leaks and seepage caused by vibration and thermal expansion. Formulated to meet or exceed performance standards for long-term salability, durability and handling, this material is used on OEM production lines and specified in their service parts programs. Temperature range -75�F to 450�F (-59�C to 232�C) continuous, 500�F (260�C) intermittent; resists ATF, coolant, oil and other shop fluids. Sensor-safe. Fleet-tested.
