Frequently Asked Questions

What is aircraft fuel tank sealant?

add

Aircraft fuel tank sealant is used to create a strong seal on integral fuel tanks, pressurized cabins, and other areas of the aircraft fuselage that are subject to contact with aircraft lubricants, fuels, oils, and water.

Can sealant be used on fuel tanks?

add

Yes, specialized sealant can be used on aircraft integral fuel tanks because aircraft fuel tank sealant resists the corrosive effects of sulfur compounds commonly found in jet fuels.
