Best Rtv For Differential Cover (2024 Update)
If you're looking for the best RTV for your differential cover, there are a few important factors to consider before buying. RTV (Room Temperature Vulcanizing) is used to create a tight seal between your differential cover and the housing, preventing oil leaks and securing your differential for optimal performance.
Firstly, make sure to choose an RTV that is specifically designed for high-pressure applications, such as those found in differentials. Look for an RTV with a high PSI rating and that can withstand extreme temperatures and heavy loads.
Secondly, consider the viscosity of the RTV. A more viscous RTV will be easier to apply and spread evenly, creating a more secure seal. Additionally, choose an RTV that will dry quickly to minimize downtime and ensure a stronger bond.
Finally, check customer reviews and consider the reputation of the brand before making your purchase. Make sure to choose an RTV that has a track record of success and is trusted by other automotive enthusiasts.
If you're still unsure which RTV to choose, ask yourself these questions: what kind of vehicle do I have, and what kind of differential cover do I need to seal? How much pressure will the RTV need to withstand, and what kind of environmental factors will it be exposed to? By answering these questions, you'll be better equipped to choose the best RTV for your differential cover.

Best Rtv For Differential Cover FAQs
Are there any special instructions for applying RTV to a differential cover?
Yes, there are some special instructions that you should follow when applying RTV (Room Temperature Vulcanizing) silicone to a differential cover. Here are some steps that you can follow:
1. Clean the surface: Before applying the RTV, make sure that the surface of the differential cover and the mating surface of the axle housing are clean and free of any oil, dirt, or debris. You can use a degreaser or brake cleaner and a clean rag to wipe down the surfaces.
2. Apply the RTV: Squeeze a bead of RTV silicone around the perimeter of the differential cover. Make sure to apply the RTV evenly and in a continuous line. Do not apply too much RTV, as it can ooze out and create a mess.
3. Spread the RTV: Use a clean finger or a plastic spatula to spread the RTV evenly over the surface of the differential cover. Make sure that the RTV covers the entire surface and fills any gaps or imperfections.
4. Install the cover: Install the differential cover onto the axle housing and tighten the bolts to the manufacturer's specifications. Allow the RTV to cure for at least 24 hours before adding any fluid to the differential.
By following these instructions, you can ensure a proper seal and prevent any leaks from the differential cover.
Can I use regular RTV sealant for a differential cover?
It is not recommended to use regular RTV sealant for a differential cover. The reason is that regular RTV sealant is not designed to withstand the extreme conditions that a differential cover is subjected to. Differential covers are exposed to high heat and pressure, and regular RTV sealant may not be able to provide a reliable and long-lasting seal.
Instead, it is recommended to use a high-temperature RTV sealant that is specifically designed for use in automotive applications. These sealants are designed to withstand high temperatures and pressures and provide a reliable and long-lasting seal.
Before applying any sealant, it is important to clean the surfaces thoroughly to ensure proper adhesion. It is also important to follow the manufacturer's instructions for application and curing times to ensure the best possible seal.
Can I use RTV sealant instead of a gasket for a differential cover?
It is not recommended to use RTV sealant as a replacement for a gasket when installing a differential cover. While RTV sealant can offer a strong and durable seal, a gasket is specifically designed to provide the proper sealing and clearance requirements for a differential cover.
Using RTV sealant instead of a gasket can lead to leaks, which can cause damage to the differential and potentially cause unsafe driving conditions. Additionally, the thickness and consistency of RTV sealant can be difficult to control, which can affect the clearance of the differential cover and lead to issues with the gears and bearings inside.
Therefore, it is best to use the recommended gasket for your specific differential cover. This will ensure proper sealing, clearance, and overall performance of your differential.
How long does RTV sealant take to dry on a differential cover?
The drying time for RTV sealant on a differential cover can vary depending on several factors. Generally, it takes around 24 hours for the sealant to fully cure and reach maximum strength. However, this can be affected by the temperature and humidity of the environment. Higher temperatures and lower humidity can speed up the drying time while cooler temperatures and higher humidity can slow it down. It's also important to note that the thickness of the application can affect the drying time. A thicker layer of sealant will take longer to dry than a thinner layer. It's recommended to follow the manufacturer's instructions for the specific type of RTV sealant being used and allow ample time for the sealant to dry and cure before operating the vehicle.
Is high temperature RTV necessary for differential covers?
High temperature RTV (Room Temperature Vulcanizing) silicone is often used for differential covers because it can withstand high temperatures and provides a good seal. However, whether or not it is necessary depends on the specific application and the type of differential cover being used.
If the differential cover is designed to be used with a gasket, then a high temperature RTV may not be necessary. The gasket will provide a sufficient seal and prevent leaks. However, if the differential cover does not come with a gasket or if the gasket is not providing a proper seal, then high temperature RTV may be necessary.
It is important to note that high temperature RTV should only be used on clean, dry surfaces. Any oil or debris on the surfaces can prevent the RTV from properly adhering and sealing. It is also important to use the appropriate type of RTV for the specific application and to follow the manufacturer's instructions for application and curing time.
In summary, while high temperature RTV can be beneficial for differential covers, its necessity depends on the specific application and the type of differential cover being used.
Should I use silicone or rubber RTV for a differential cover?
Choosing between silicone or rubber RTV for a differential cover depends on various factors. Both silicone and rubber RTV are popular choices for sealing differential covers. However, each one has its own advantages and disadvantages.
Silicone RTV is a popular choice due to its excellent temperature resistance and flexibility. It can withstand high temperatures without breaking down or leaking, making it a reliable choice for differential covers. Additionally, it is easy to apply and remove, making it ideal for DIY projects.
On the other hand, rubber RTV is a more affordable option and is widely used in the automotive industry. It provides a strong and durable seal, making it suitable for use in heavy-duty applications. However, it is not as temperature resistant as silicone RTV, and it can be more challenging to remove.
Ultimately, the choice between silicone and rubber RTV for a differential cover depends on your specific needs and preferences. If you need a high-performance seal that can withstand extreme temperatures, then silicone RTV may be the better choice. However, if you want a more affordable and durable option, then rubber RTV may be the better choice.
