Gasket Makers, Sealants & Removers
Essential Sealing Solutions for Engine and Powertrain Repairs
Gasket makers are liquid or paste compounds designed to form a flexible, airtight, and watertight seal between engine parts, effectively replacing or enhancing traditional pre-cut gaskets. Whether you're rebuilding an engine, replacing a valve cover, or sealing an oil pan, these chemical gasket solutions offer versatility that solid gaskets can't match. Gaskets prevent leaks of oil, coolant, and other fluids from between surfaces like valve covers to cylinder heads, oil pans to engine blocks, and water pumps to the engine.
Modern gasket makers come in several formulations, each engineered for specific operating conditions. RTV gasket makers are available in different colors—Black, Grey, and Red—each with different product benefits for applications like added rigidity for high vibration areas or maximum flexibility for dissimilar metals. Black RTV excels in oil resistance and flexibility, making it ideal for oil pans and transmission covers. Grey RTV provides maximum rigidity for close-tolerance applications like water pumps and timing covers, while red RTV withstands extreme temperatures and thermal cycling for exhaust-adjacent components.
Why Gasket Makers Matter in Vehicle Maintenance
Gasket makers are resistant to the high heat levels, pressure, and vibration that an engine creates, offering superior sealing performance compared to traditional cut gaskets in many situations. They fill surface imperfections and compensate for minor warping or machining irregularities that would otherwise cause leaks. For restoration projects where original gaskets are no longer available, or for custom fabrication work, liquid gasket makers provide an invaluable solution.
Beyond standard RTV formulations, specialty products include anaerobic gasket makers that cure in the absence of air for metal-to-metal applications, fuel-resistant sealants for carburetor and fuel system work, and gasket removers that simplify disassembly without damaging mating surfaces. Choosing sensor-safe formulations prevents contamination of oxygen sensors and catalytic converters in modern vehicles.
