Red Hi-Temp RTV Silicone Gasket Maker, 85 g Tube

Dynatex 143367 is Dynatex® Red Hi-Temp RTV Silicone Gasket Maker in an 85 g (≈ 3 oz) tube. This one-component, paste-type silicone cures on exposure to moisture to form a tough, flexible seal that resists oil, water, antifreeze, transmission fluids, and vibration. Engineered for demanding environments, it is oxygen-sensor safe and maintains integrity at elevated temperatures up to 650 °F (343 °C), making it ideal for high-heat engine, transmission, and exhaust sealing applications.
