Flat Free Tire Sealant

Flat Free is a revolutionary chemical solution tire sealant that when installed inside a tire, will provide permanent air-loss protection for the entire life of a tire. This space-age product combines an ethylene-glycol based solution with natural and artificial fibers, adhesion agents, drying agents, corrosion inhibitors and other solids. Flat Free is an exclusive formula designed to remain fluid and to keep fibers and solids in constant suspension. Because there is not settling of the solids and fibers, Flat Free is always ready to work for you!
