FAQ:

Q: Can you use sealant instead of gasket for oil pan?

A: It is fine to use the correct RTV sealant instead of a gasket if used in the right application (oil, high temp, fuel). Not, however, if the gasket thickness is required to produce a specific amount of clearance. RTV sealant is better than primitive gaskets in most applications ie.

Q: What is the best thread sealant for gasoline?

A: For gasoline, regular old gasoline resistant Aviation Form-a-gasket Number 3 is the best option. Another product also offered by Permatex is the High Temperature Thread Sealant. Tech data on this sealant says it has medium solvent resistance and is recommended for fuel sender type applications.

Q: Should I use gasket sealant or not?

A: It is a widely-held misconception that gaskets need sealant. Manuals for most motorcycle manufacturers specify that sealant is unnecessary , but it can even be harmful. When a silicone-based or other sealant is used, it can interfere with the proper function of the engine.

Q: Is Sikaflex fuel resistant?

A: Sikaflex Tank N is one of only a handful of joint sealants on the market today specifically designed to be resistant to oils and petroleum based fuels . (Please see data sheet for full list) Sika Tank N is used in areas for the storage, filling and handling of water polluting liquids.
