This premium RTV silicone sealant delivers long-lasting sealing performance while resisting oil, transmission fluids, gear lube, and other automotive chemicals. That makes it a top choice for professional mechanics and DIY car repair enthusiasts who demand durability and precision.
Maximum Oil Resistance
The standout feature of this product is its maximum oil resistance. Ordinary silicone sealants can weaken when exposed to motor oils and automotive fluids. However, Permatex Ultra Black maintains a strong bond, making it ideal for components that come in direct contact with oil. This includes oil pans, valve covers, timing covers, differential covers, and transmission pans.
High-Flex Formula for Engine Movement
Modern engines expand, contract, and vibrate continuously due to temperature fluctuations and mechanical movement. A gasket that cannot flex will eventually crack and leak. This sealant offers excellent flexibility and vibration resistance, allowing it to adjust with engine movements without losing its sealing properties.
Sensor-Safe and Non-Corrosive
Older sealants often contained chemicals that caused corrosion or damaged engine sensors. Permatex Ultra Black is formulated to be sensor-safe and non-corrosive, making it suitable even for the latest vehicles equipped with oxygen sensors and other electronic monitoring systems. You can confidently use it without worrying about component damage.
High-Temperature Performance
Under-hood temperature can reach extreme levels. With a heat tolerance of up to 500°F (260°C), this RTV silicone gasket maker performs reliably in both high-temperature and heavy-duty applications. Whether you’re working on a daily commuter or a high-performance vehicle, this product ensures long-lasting sealing strength.
Easy Application for DIY & Professional Use
Packed in a convenient 3 oz tube, the sealant is easy to apply, spreads smoothly, and cures to a durable rubber-like gasket. The fast and efficient curing time ensures strong adhesion and leak-proof performance. Whether you’re repairing an oil leak or building an engine, this product provides professional-level results.
Final Verdict
Permatex 82180 Ultra Black RTV Silicone Gasket Maker is one of the most dependable and durable sealants for oil-exposed environments. Its flexibility, temperature resistance, and sensor-safe formula make it a must-have for vehicle maintenance and repair work. If you want a long-lasting, leak-proof solution for engine components, this is a top-tier product worth keeping in your toolbox.
