POR-15 Fuel Tank Sealer

POR-15 Fuel Tank Sealer was formulated and developed in our own laboratories due to the demand for a high-tech sealer impervious to all fuels, including the new Stage II fuels which have a high alcohol content. This gas tank sealant has superior strength and fuel resistance. Also, this gas tank liner stops rust, corrosion, and small fuel leaks. Fuel tanks must be free from plastic parts, contamination, and be structurally sound before applying sealer.

Color: Silver

Coverage: 

  • 8 fl oz is enough to coat the inside of a 6 gallon fuel tank
  • 32 fl oz (quart) is enough to coat the inside of a 25 gallon fuel tank

Formerly U.S. Standard Fuel Tank Sealer

Rusted 8 gal. generator tank.

One pint of gray sealer covered entire inner surface. Dried hard in 96hrs as recommended. We'll work hard to keep tank filled between usage an drain and fill before next usage if greater than one year.

Proper chemical interaction is essential for achieving the best possible bond of the sealer to the inside of the tank. Fuel Tank Sealer does not adhere well to plastic. If your fuel tank contains plastic components inside, they should be removed before applying Fuel Tank Sealer.
