As an expert in fluid systems and their maintenance, I can provide you with some guidance on selecting the right sealant for gasoline fittings. When dealing with gasoline fittings, it is crucial to choose a sealant that offers excellent chemical resistance to fuels and oils, ensuring a leak-free and safe connection.
Firstly, it is important to understand that gasoline is a volatile and corrosive substance that can degrade many types of sealants over time. Therefore, the sealant you choose must be specifically designed to withstand the chemical properties of gasoline without breaking down or becoming brittle.
Thread Sealants for Gasoline Fittings:
1. PTFE Tape (Plumber's Tape): This is a common choice for many mechanics due to its ease of use and availability. PTFE tape is made from polytetrafluoroethylene, which is chemically inert and resistant to a wide range of chemicals, including gasoline. It forms a good seal when wrapped around threaded fittings and tightened. However, it's worth noting that while PTFE tape is effective, it may not be the most durable option for high-pressure applications or where frequent disassembly is required.
2. Anaerobic Thread Lockants: These are liquid sealants that cure in the absence of oxygen, forming a solid plastic when confined in a threaded connection. They are resistant to a variety of chemicals, including gasoline, and can provide a strong, durable seal. Anaerobic thread lockants are suitable for both static and dynamic sealing applications and are often used in automotive and industrial settings.
3. Fluoroelastomer (FKM) Sealants: These are synthetic rubber sealants that offer excellent resistance to oils, fuels, and chemicals. They are designed for high-temperature applications and can maintain their sealing properties under the harsh conditions often found in gasoline systems.
4. Silicone Sealants: While not as chemically resistant as some other options, silicone sealants can be used in certain gasoline fitting applications where the sealant will not be in direct contact with the fuel. They are flexible, easy to apply, and can provide a good seal in low-pressure situations.
5. Specialized Gasoline-Resistant Sealants: There are also sealants on the market that are specifically formulated to resist gasoline and other fuels. These products are designed to maintain their sealing properties even when exposed to the harsh chemicals found in gasoline.
When choosing a sealant, consider the following factors:
- Chemical Resistance: Ensure the sealant can resist the specific chemicals found in gasoline.
- Temperature Range: The sealant should be able to withstand the operating temperatures of the gasoline system.
- Pressure Rating: The sealant must be able to handle the pressure within the gasoline system.
- Ease of Application: Some sealants are easier to apply than others, which can be an important consideration for DIY mechanics.
- Longevity: Look for a sealant that will maintain its sealing properties over time without breaking down or becoming brittle.
In conclusion, while PTFE tape is a popular choice due to its ease of use, there are other options available that may offer better performance and longevity in gasoline fittings. It is important to consider the specific requirements of your application and choose a sealant that meets those needs.

To choose the appropriate thread sealant, look for it's chemical resistance to fuel (diesel or gasoline) or oil running through the line. Backyard mechanics will tell you they've used regular old gas resistant teflon tape (yellow stuff) with success.
