9.6 worth the money9.6 Simple to useMain highlights- SAFE FOR CATALYTIC CONVERTERS AND ELECTRONIC SENSORS: The innovative formulation ensures that it does not damage catalytic converters or interfere with sensitive electronic sensors, making it safe for modern vehicle systems. Unlike some sealants that can emit harmful substances affecting emissions control devices, this polysiloxane-based compound remains chemically stable and non-reactive with vehicle components. This makes it an excellent choice for use in engines, transmissions, and other automotive applications where maintaining system integrity is essential.
- REPLACES TRADITIONAL GASKETS: Engineered to serve as a highly efficient alternative to conventional gaskets, this product eliminates the need for other materials. By forming a strong, flexible, and durable bond, it creates customised seals directly on the required surfaces. The application process is simplified, reducing installation time while improving reliability. Unlike traditional gaskets that may degrade, crack, or require frequent replacement, this advanced sealant offers a superior long-term solution, adapting perfectly to the shape and needs of each component without the limitations of pre-cut gaskets.
- IDEAL FOR ENGINE COMPONENTS AND VARIOUS APPLICATIONS: Perfect for use in a wide range of applications, including engine components such as cylinder-head covers, oil crankcases, transmissions, water pumps, and thermostats. Its ability to create strong and flexible seals makes it ideal for both automotive and industrial settings. Whether used for routine maintenance, repair work, or performance upgrades, this high-performance sealant ensures a reliable and long-lasting solution.
- HIGH-TEMPERATURE RESISTANT SEALANT: Specially designed to withstand extreme temperatures, this polysiloxane-based material remains effective in both low and high thermal conditions. It endures continuous exposure to temperatures as low as -40°C, ensuring flexibility and stability in cold environments. Simultaneously, it provides excellent heat resistance, tolerating up to 232°C continuously and 260°C intermittently. This makes it a highly reliable solution for use in demanding automotive and industrial applications where exposure to extreme heat and cold is a concern.
- EXCELLENT RESISTANCE TO OILS, FLUIDS, AND TOXIC GASES: Designed for durability and high performance, this flexible sealant effectively resists a variety of harsh substances. It maintains a secure seal against oils, transmission fluids, antifreeze, grease, and water, preventing leaks and ensuring proper functionality of mechanical components. Additionally, it withstands exposure to smoke and hot toxic gases, making it suitable for automotive engines and exhaust systems where these elements are present. This superior resistance ensures reliable operation under demanding conditions, reducing the risk of damage caused by fluid contamination or environmental exposure.
