Aircraft fuselage and fuel tank sealants from SkyGeek are designed to prevent corrosion, stop leaks and keep fuel tanks in perfect working order. A cracked fuselage can spell big trouble when you're up in the sky, so it's important to check your tank regularly for cracks and corrosion. You can also use fuselage sealants on seams, bolt holes and any other potential weak spots to ensure the integrity of the fuel tank during flight, preventing any mid-air emergencies. Aircraft fuselage sealants from SkyGeek are designed to be non-reactive with aircraft fuel and are capable of withstanding a wide range of temperatures, allowing them to protect the aircraft when it's on the ground or up in the air. The sealants are made to be applied with a sealant gun and go on smoothly, filling gaps or cracks with ease to provide complete protection. You may need to use a spatula or other spreading device to smooth the fuel tank sealer after it is extruded and to press the mixture into any holes or cracks. We also carry spatulas and spreaders to make this job easier.

Fuel tank sealants are available in a wide range of formulations to suit your needs. The curing times and temperature resistances vary from product to product, making it easy to find the right formula for your needs. Use a fast-curing sealant for urgent repairs or a slow-curing, long-lasting sealant for casual maintenance needs and assemblies. Our sealants are made by top manufacturers in the industry, including 3M, Flamemaster and PPG Aerospace so you can feel confident using them on your aircraft. These top brands are known for reliable performance and consistent results, protecting aircraft fuel tanks flight after flight. Best of all, our fuselage sealants are priced low for an excellent value. Many of our sealants are even pre-packaged in a dispensing cartridge for convenience, though some are sold in larger containers and can be transferred to your favorite brand of cartridge before using. Larger containers of airplane fuel tank sealant generally offer a better value for commercial users while smaller, pre-loaded cartridges are more convenient for the DIY-er. If you choose a bulk size container of sealant, empty cartridges and sealant guns are also available from SkyGeek.

If you have any additional questions, we encourage you to check out our knowledgeable Help Center or to reach out to one of our Geeks. At SkyGeek, we carry the tools and consumables you need to keep your aircraft in perfect condition.
