Aircraft fuselage and fuel tank sealants from SkyGeek are designed to prevent corrosion, stop leaks and keep fuel tanks in perfect working order. The high-quality sealants can be used on seams, bolt holes and any other potential weak spots to ensure the integrity of the fuel tank during flight. Aircraft fuselage sealants 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 applied with a sealant gun and go on smoothly, filling gaps or cracks and providing complete protection.

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. Our sealants are made by top manufacturers in the industry, including 3M, Flamemaster and PPG Aerospace. They offer reliable performance, consistent results and an excellent value. Many sealants are pre-packaged in a dispensing cartridge for convenience, though some are sold in larger containers and can be applied using your favorite brand of cartridge. Empty cartridges are also available from SkyGeek.
