Description
Fuel tank leaks are a serious hazard in the cockpit—they compromise safety, create unpleasant odors, and can lead to costly downtime. The PPG PR-1422 Fuel Tank Sealant is formulated to repair and seal internal fuel tank surfaces, addressing pinhole leaks, corrosion damage, and seams that weep fuel. This sealant works on aluminum and steel tanks commonly found in general-aviation aircraft, helping owners restore tank integrity without a full replacement.
Application requires proper surface preparation and may involve draining the tank, cleaning affected areas, and following the manufacturer’s cure schedule before returning the aircraft to service. Verify compatibility with your specific tank material and fuel type before use. Many operators choose tank sealant as a cost-effective alternative to tank removal or overhaul, though complex structural damage or extensive corrosion may still require professional tank repair or replacement. Always consult your maintenance manual and consider professional guidance for critical fuel system work.
