Ford Genuine Fluid TA-31 RTV Sealant Review
By SellySell Editorial Team | Last updated: June 11, 2026
Ford Genuine Fluid TA-31 RTV Sealant is a high-temperature silicone gasket maker for automotive sealing jobs. The article link points to ASIN B000NUD02W. Because this edit uses only the supplied HTML and no live product lookup, all technical details below are kept conservative and should be checked against the current Amazon listing or Ford service guidance before use.
Verdict
Ford Genuine Fluid TA-31 is best for buyers who need a viscous, non-corrosive RTV sealant for demanding engine sealing work. It is most useful when the surface prep, bead size, and cure time are controlled carefully. The main trade-off is patience. Heavy-duty service can expose weak application technique fast, so clean surfaces and full cure time matter.

What Is This Product?
Ford Genuine Fluid TA-31 RTV Silicone Sealant is a high-viscosity gasket maker for automotive sealing work. The supplied article describes it as a non-corrosive, high-temperature RTV that can be used around diesel engine service areas such as cylinder heads, valve covers, and intake manifolds when the application matches the service manual.
The sealant is meant to fill small sealing gaps and form a flexible gasket after curing. It is not a shortcut for damaged parts, warped flanges, poor torque sequence, or dirty mating surfaces.
Who It Is For
This sealant is for technicians and experienced DIY users who need an RTV gasket maker for engine-related sealing jobs. It makes the most sense for users who can follow the manufacturer’s service procedure, prepare the surface correctly, and allow the RTV to cure before putting the part back into hard service.
It may also suit owners working on Ford diesel platforms mentioned in the supplied article, including 7.3L Power Stroke, 6.0L, and 6.4L engines, but compatibility should be confirmed with the current service manual before use.
Who Should Skip It
Skip it if the repair requires a pre-formed gasket, an anaerobic flange sealant, thread sealant, fuel-system sealant, or a sealant with a different chemical rating. Also skip it if you cannot leave the vehicle or part undisturbed long enough for proper cure.
Buyers should also avoid using RTV on surfaces that are oily, wet, painted in a way that may lift, or too smooth to bond well without preparation. RTV failure is often caused by poor surface prep, too much material, or early reassembly load.
Key Features
- High-temperature use: The supplied article lists 390°F continuous temperature resistance. Confirm this on the live listing or product data sheet before using it near extreme heat.
- Non-corrosive chemistry: The article describes TA-31 as non-corrosive, which is useful around metal engine components when the application is correct.
- High-viscosity bead control: A thicker RTV can help maintain a steady bead and fill small gaps, but too much product can squeeze out and cause problems.
- Fast skin time: The article lists a 5 to 20 minute skin time depending on bead size. Work within the skin window and follow the service instructions.
- Full cure window: The article lists 24 to 48 hours for full cure, depending on humidity, temperature, and thickness.
Real-World Use
For the best result, clean both mating surfaces until they are dry and free of oil, coolant, old gasket residue, and loose corrosion. Smooth castings may need light surface preparation if the service procedure allows it.
A small, steady bead is usually better than a heavy bead. The supplied article mentions 1/16 to 1/8 inch for many sealing tasks and 1/8 to 3/16 inch for valve cover use. Use the bead size required by the repair manual rather than guessing.
Heavy-duty service adds heat cycles, vibration, pressure changes, and fluid exposure. The trade-off is that the seal can be dependable only when the joint is prepared and cured correctly. Rushing reassembly, over-applying RTV, or torquing too early can reduce reliability.

Frequently Asked Questions
Is This Sealant Safe for Use on Aluminum and Painted Surfaces?
The supplied article describes TA-31 as non-corrosive, which supports use around aluminum when the application is compatible. Painted surfaces should be tested carefully because adhesion can depend on the paint, surface prep, and exposure conditions.
Can TA-31 Be Used for Gasket Replacement on Gasoline Engines?
It may be usable on gasoline engine applications when the service manual calls for this type of RTV. Do not use it as a universal gasket replacement. Confirm the sealant type, bead location, torque sequence, and cure time for the exact engine.
What Is the Shelf Life Unopened at Room Temperature?
The supplied article lists approximately two years unopened at room temperature. Storage can affect shelf life, so keep the tube sealed, cool, and dry, and check the package date or manufacturer guidance before use.
Is It Compatible With RTV Primers or Adhesion Promoters?
Primer compatibility should be verified with the product instructions or manufacturer guidance. If a primer or adhesion promoter is not specified for the repair, do not assume it will improve the result.
Does TA-31 Meet OEM or Industry Certification Standards?
The supplied article does not provide a confirmed certification. Check the current Amazon listing, product label, Ford service information, or manufacturer data before relying on any formal standard.
What Performance Trade-Offs Should Be Expected in Heavy-Duty Service?
The main trade-offs are cure time and application sensitivity. TA-31 can be useful in demanding heat and fluid exposure, but heavy-duty use gives little margin for poor prep. Dirty surfaces, excessive bead size, short cure time, and uneven compression can lead to leaks.
Final Verdict
Ford Genuine Fluid TA-31 RTV Sealant is a practical choice when your repair calls for a high-temperature, non-corrosive RTV gasket maker and you can follow the proper cure process. It is best treated as a service-specific sealing product, not a universal fix.
Buy it if your vehicle manual, part requirement, or technician guidance points to TA-31 or an equivalent RTV. Skip it if you need a different gasket type, cannot verify compatibility, or cannot allow enough cure time.
