Tank Sealer on Air Compressor Tanks: Quick Facts

Works on: Steel air compressor tanks

Fixes: Condensation rust and pinhole leaks

Most air compressor tanks develop rust over time from the condensation that forms inside the tank as compressed air cools. That rust can eventually eat through the tank wall and cause a leak, so many owners prep and seal the inside of their compressor tanks to stop the problem before it starts.

Already have a pinhole leak? For air compressor tanks with a pinhole leak about the size of a pin tip, the KBS Tank Sealer System will seal up that leak and protect it from getting any larger.

Use the same KBS 3-Step System as any other steel tank: clean with KBS Klean, etch with RustBlast, then seal with Gold Standard Tank Sealer.

What causes rust inside an air compressor tank?
