Product Details
✓ALL-POWERFUL SEALING: This silicone gasket maker works on a variety of surfaces, including metals like stainless steel, aluminum, and brass, even if they are plated or slightly contaminated by oil. It is also effective on glass, wood, and other materials that require sealing. Once applied, it sets fully in 24 hours, allowing easy disassembly. The gasket's power lies in its ability to withstand extreme temperatures, resist chemicals, and offer long-lasting durability across many applications.
✓VERSATILE APPLICATIONS: Ideal for a wide range of uses, this sealant is perfect for automotive, motorbike, and industrial applications. It works on oil pans, exhaust manifolds, timing covers, water pumps, valve covers, thermostat housings, and more. Additionally, it is great for sealing mechanical assemblies, 3D printers, ovens, refrigerators, pipe joints, valves, and cable entry seals. Its versatility makes it an essential product for both DIY and professional use.
✓SUPERIOR PERFORMANCE: This RTV silicone gasket maker outperforms conventional silicone by offering better oil resistance and greater flexibility than cut gaskets. It is safe, non-corrosive, and has low odor. Designed to endure extreme temperatures ranging from -60º C to 280º C, it provides superior adhesion, making it ideal for high-performance sealing tasks. It’s engineered to withstand regular wear and tear while maintaining a durable and effective seal.
✓EASY APPLICATION: Applying this gasket maker is simple—just clean the surface, apply the sealant, and let it cure. The product forms a tough, waterproof seal that fills tiny gaps and resists moisture, ensuring no shrinkage, dripping, or cracking. It is particularly effective for automotive applications, providing a long-lasting seal that resists oil, coolant, and other automotive fluids. Perfect for oil pans, valve covers, and water pumps, it prevents leaks in harsh environments.
✓DURABLE, LEAK-PROOF & REUSABLE: This sealant forms a strong, durable seal that resists cracking, shrinking, and vibration, keeping your repairs leak-free over time. It is ideal for engine components and other applications that require a tough bond under harsh conditions. The caulking tube design allows for precise, mess-free application, and once used, excess sealant can be cured and reused for future projects, saving both time and money.
