J-B Weld Hi-Temp Silicone Gasket Maker & Sealant Red (85g) is a high-performance RTV (Room Temperature Vulcanized) silicone gasketing material. Designed for demanding applications, this red silicone sealant creates a tough, waterproof seal on most surfaces, even in high-temperature environments. Ideal for mechanical assemblies where continuous temperatures up to 287°C (550°F) or intermittent temperatures up to 343°C (650°F) are encountered. Once cured (through exposure to air moisture), it won't shrink or crack and offers excellent resistance to weathering. This sensor-safe sealant is particularly well-suited for various automotive applications.
