About
Fuel Tank Sealant PR-1422 is a high-performance, two-component polysulfide sealant specifically formulated for aircraft fuel tank applications. This aerospace-grade material is manufactured through precise chemical synthesis of polysulfide polymers with specialized curing agents and additives. The sealant provides exceptional resistance to aviation fuels, hydraulic fluids, and extreme temperature variations from -65°F to 250°F. Its primary uses include sealing fuel tank joints, bolt holes, and structural connections in both commercial and military aircraft. Key properties include excellent fuel resistance, flexibility, durability, and adherence to stringent aviation specifications like MIL-S-8802. Makers and aerospace manufacturers purchase PR-1422 for critical fuel system maintenance, aircraft repairs, and new construction projects where fuel containment integrity is paramount. The material cures to form a resilient, long-lasting seal that maintains performance under constant fuel exposure and mechanical stress.
