What is FlatSeal?

Flat Seal is designed to seal


 Tread punctures
 Bead leaks
 Rim leaks
 Tube, tire or wheel-related leaks

Flat Seal has a revolutionary chemical structure that causes this tire enhancer to continuously remain fluid so that it will immediately fill and seal any hole (up to 1/4") in the tread area where air can escape from the tire.

Because of this, Flat Seal tire life enhancer gives you the benefit of much longer tire life coupled with less downtime and lower maintenance costs. Additionally, you will receive savings from maintaining proper air pressure.








Characteristics of Flat Seal


This space-age product combines an ethylene-glycol based solution with natural fibers, artificial fibers, adhesion agents, drying agents, corrosion inhibitors, and other solids.

It is designed to keep the fibers and solids in constant suspension. Because there is no settling of the solids and fibers, Flat Seal tire life enhancer is always ready to work for you -- no mixing, stirring, or other preparation is necessary.

The adhesion properties in Flat Seal tire life enhancer -- coupled with the fact that it remains fluid when installed in the tire -- provides constant protection for all parts of the tire. Aerosol inflators provide temporary fixes at best.


Flat Seal is ready for use. NO mixing or special preparation is required. In fact, Flat Seal's formulation is non-toxic, non-flammable, and environmentally friendly. So much so, that it even meets the requirements of the California Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65).

Flat Seal also does not void tire manufacturer warranties or affect wheel balance if properly installed.
