POR-15 High Performance Fuel Tank Sealer, 236ml (8oz), Stops Leaks and Seals Metal Fuel Tanks Against Rust, Corrosion, and Ethanol-Blended Fuel Damage
A leaking fuel tank grounds an aircraft and a corroding tank interior left untreated becomes a contamination, structural, and fire risk that compounds over time. Supplied by JHEARs Aerospace, POR-15 Fuel Tank Sealer is a high-performance coating that stops active leaks, seals pinholes, and forms a permanent, fuel-resistant barrier on the interior surface of metal fuel tanks that protects against rust, corrosion, and the degrading effects of ethanol-blended fuels that accelerate metal deterioration in older tank designs not originally built for ethanol exposure. Once cured, the coating forms a rock-hard, flexible barrier that does not crack, peel, or dissolve in contact with petrol, diesel, or ethanol-blended fuels.
Compatible across a range of fuel types and proven in both aircraft and vehicle fuel tank restoration applications, POR-15 Fuel Tank Sealer is the product used when the tank needs to be made serviceable and protected for the long term rather than patched as a temporary measure. The 236ml (8oz) size is suited to smaller tanks and targeted repair applications, providing a practical working quantity for the task without the waste of a larger format container when full tank coating is not required.
Spec: POR-15 Fuel Tank Sealer, 236ml (8oz). High-performance fuel-resistant internal tank coating. Stops leaks and seals pinholes in metal fuel tanks. Resistant to petrol, diesel, and ethanol-blended fuels. Protects against rust and internal corrosion. Cures to a hard, flexible, permanent barrier coating.
Who this is for: Aircraft owners and mechanics addressing active fuel tank leaks or pinholes on metal fuel tanks, maintenance engineers restoring and protecting older metal fuel tanks subject to internal corrosion and ethanol-fuel degradation, and anyone who needs to make a leaking or corroding metal fuel tank serviceable and protected for long-term use.
FAQ
Does POR-15 Fuel Tank Sealer require any surface preparation before application?
Yes. Proper surface preparation is essential for adhesion and effectiveness. The tank interior must be thoroughly cleaned and degreased to remove fuel residue, rust, and contamination before the sealer is applied. POR-15 recommends using their dedicated tank preparation products including a cleaner-degreaser and metal prep solution before the sealer coat. Skipping preparation steps will compromise adhesion and the long-term integrity of the coating.
Is POR-15 Fuel Tank Sealer approved for use in aircraft fuel tanks?
POR-15 Fuel Tank Sealer is widely used in the automotive and motorsport sectors for metal fuel tank restoration. For use in aircraft fuel tanks, verify that the product is appropriate for your specific aircraft type and fuel system, and consult your aircraft maintenance manual and applicable airworthiness authority guidance before application in a certificated aircraft fuel system. Owner-maintained experimental and homebuilt aircraft have more flexibility in product selection.
How much tank interior area does 236ml cover?
Coverage depends on the number of coats applied and the internal surface area of the tank. For small fuel tanks and targeted pinhole repair applications, 236ml is typically sufficient. For larger tanks requiring full internal coating, a larger quantity will be needed. Calculate your tank's internal surface area and refer to the POR-15 coverage data before purchasing to ensure you have sufficient product for the job.
