Permatex 81422 is a sensor-safe, high-temperature RTV silicone gasket maker in a 3 oz. tube, formulated specifically for oxygen sensor-equipped engines. The compound maintains a temperature range of -65F to 650F (-54C to 343C) intermittent, resisting automotive and shop fluids throughout that range. Because it is oxygen sensor-safe, it will not foul sensors the way conventional silicone formulas can. This is the first-generation high-temp gasket maker from Permatex, suited for use anywhere a formed-in-place gasket seal is required on high-heat engine applications. Sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
