Maximum Performance Gasket Sealing

The Permatex Ultra Red Gasket Maker is designed for high-load, high-temperature applications where maximum reliability is required. This sensor-safe, silicone-based formula is engineered to withstand temperatures up to 650°F (343°C) and is resistant to oil, transmission fluid, and coolant. It is the perfect choice for high-performance engines that generate significant heat and vibration.

Why Choose Ultra Red?
