Seal engine blocks, oil pans, timing covers, and more with confidence using the Ford Motorcraft TA31 Silicone Sealant—the same formula trusted at Ford and Power Stroke factories worldwide. This alkoxy-cure, gray RTV was engineered for high-temp sealing, providing leak-free performance in modern diesels, turbocharged, and severe-duty applications.
TA31 is non-corrosive to aluminum and sensors, cures quickly, and delivers OE-grade resistance to oil, coolant, and vibration—protecting against oil pan, timing cover, and engine block leaks. Apply to clean flanges, assemble components, and your repair cures fast, withstanding extreme temps, pressures, and fluids for miles.
Each 5 oz tube (part numbers FSGSTA31, TA31, TA-31) meets all Ford and Motorcraft requirements, and is warranty-backed for 2 years and unlimited mileage. For every major reseal or powertrain build, insist on the original: Motorcraft TA31.
