PPG Aerospace® PR1440 A-1/2 Gray AMS-S-8802C Class A-1/2 Spec Fuel Tank Sealant in the 6 oz 654-SemKit is a two-component, manganese dioxide-cured polysulfide formulated for rapid application and controlled cure in production or maintenance environments. It forms an elastic, fuel-resistant barrier that adheres securely to common aerospace substrates such as aluminum, titanium, and composites, protecting against aviation fuels, oils, and hydraulic fluids in demanding temperature and pressure ranges. Ideal for integral fuel tanks, fuselage joints, access panels, and structural interfaces, it maintains sealing integrity under vibration, flexing, and thermal cycling, supporting efficient assembly and reliable long-term performance.
