AG330 High-Temp RTV Silicone Gasket Maker & Sealant, Red, 10.5 oz, 572 DegF Heat Resistant

AG330 High-Temp RTV Silicone Gasket Maker & Sealant is a heavy-duty, high-performance solution designed for demanding sealing, gasketing, and bonding applications exposed to extreme heat. Withstanding continuous temperatures up to 482°F and temporary spikes up to 572°F, this red RTV Room Temperature Vulcanizing silicone is ideal for automotive, industrial, and household applications. It forms durable, flexible gaskets that resist cracking, shrinking, and migration caused by thermal cycling, while maintaining airtight and leak-proof seals. Use it to seal engine components, stoves, boilers, pumps, exhaust systems, and more. Curing via an acetoxy system, it offers superior adhesion and long-lasting elasticity-even under pressure, oil, water, and harsh chemicals. This 100% silicone formula is solvent- and isocyanate-free, making it a safe and effective choice for high-temp environments.
