Frequently Asked Questions (FAQs)

1. Is it better to use a gasket or RTV on a differential?

Using a Fel-Pro differential cover gasket is recommended for sealing a differential cover. These gaskets are designed specifically for this purpose and help seal imperfect sealing surfaces.

2. When should you not use RTV sealant?

If your assembly will be exposed to gasoline, it is not advisable to use RTV sealant. In such cases, a solvent-based gasket maker should be used instead.

3. Is RTV stronger than silicone?

When choosing between RTV and silicone sealants, it can be a complex decision. Pure silicone sealant has stronger adhesion, less shrinkage, lower temperature application, and better resistance to weathering compared to extended silicone sealant.

4. Can I use silicone instead of RTV?

RTV silicone is generally more expensive than regular silicone, which limits its usage. Many people prefer using regular silicone due to its lower cost.

5. Do you use sealant on Felpro gaskets?

Most Fel-Pro gaskets do not require the use of sealant. However, in certain cases, such as mating gaskets or filling gaps, sealant may be necessary.
