Frequent question: What kind of rubber is gasoline resistant?

The best fuel resistant gasket material for gasoline is Nitrile (Buna-N), a closed-cell sponge rubber material that provides excellent gasket material for sealing applications that require resistance to gasoline, oil, fuels, as well as solvents, hydraulic fluids, and mineral and vegetable oils.

Is nitrile rubber gasoline resistant?

Nitrile is highly resistant to oils and solvents, such as engine oil, gas, alkalis, acids, and petroleum-based hydraulic fluids. This makes it useful for components frequently exposed to harsh chemicals and fuel.

Is neoprene rubber resistant to gasoline?

It’s a very heat resistant rubber. When compared with natural rubber, neoprene resists gas permeation more and can function in temperatures up to 275 degrees Fahrenheit (F).

What is the best sealant for gasoline?

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.

Is natural rubber gasoline resistant?
