FAQ - Frequently Asked Questions

  • What is Flat Seal?


Flat Seal is a chemical product that when installed inside a tire, will provide full time protection against air loss for the legal life of the tire as well as extend the life of the tire by maintaining proper inflation and preventing under inflation.

  • How does Flat Seal prevent rim and bead leaks?


The escape of high pressure air from the tire into the atmosphere draws fibers and particles to the area of the escaping air. The leak is thus located and sealed.

  • How does Flat Seal seal a hole in the tread of the tire?


Flat Seal is drawn to the area of the escaping air. As the tire rotates and strikes the surface of the road, the hole is stretched open and the polyethylene chips and other fibers enter the cavity. The fibers wrap around the polyethylene chips and form a permanent and flexible plug, similar to the action of a beaver dam.

  • What is the shelf life of Flat Seal?


The shelf life of Flat Seal is practically indefinite as long as the container is closed and no evaporation occurs.

  • Will Flat Seal rust the rim of the tire?


Not at all. Flat Seal contains anti-corrosive agents to prevent corrosion from occurring as well as to deal with any corrosion on the tire prior to installation.

  • Does Flat Seal run to the bottom of the tire when the tire is not in motion?


No! Flat Seal contains specially selected compounds which prevent this from happening. The sealant remains in place covering the interior of the tread at all times.

  • Can Flat Seal be used in a tube tire?


Yes. However, it is vital to remove the penetrating object. Failure to do so will result in the object flexing in the tire and shredding the tube until it is destroyed. Although we can't guarantee the sealant to always permanently seal a puncture due to the condition of the tube, we do guarantee that as long as the tire is in motion, you will reach your destination, and then, should some damage have occurred to the tube, it may lose air.

  • Will Flat Seal seal a puncture in the sidewalls of the tire?


No. There is too much flexing in the sidewalls and a temporary plug would be a safety factor.

  • Will Flat Seal dry out in the tire?


No! Flat Seal will always stay in the same condition as it was when it was inserted into the tire because the tire is a closed container and no evaporation of the liquid can occur.

  • Who are some of the users of Flat Seal?


Users are many and varied. They include: construction companies, police forces, municipalities, golf courses, pallet manufacturers, truck fleets, airports, quarries, industry, utilities, RV manufacturers, new car dealers, used car dealers and more.

  • Can Flat Seal be used in heavy-duty equipment?


Yes. Flat Seal is designed for use in any pneumatic tire. For tires requiring an extra amount of protection, such as those on construction equipment, or tires used in rugged off-road environments, we have an industrial formulation.

  • What tools do I need to install Flat Seal? (Bottle or 5-Gallon)?


The tools needed are: Valve core remover - Tire pressure gauge - Source of air

  • What is the difference between Flat Seal and other similar products?


Other liquid sealants are either paste, solvent, gel or water-based, which consequently dry out at low temperatures. Many of the liquid tire sealants congeal, which can cause balancing problems and alteration of the rubber composition. That, in turn, shortens the life of the tire. Flat Seal is Glycol based and will not break down or dry up inside the tire. Flat Seal, if properly installed, will not affect tire balance.

  • What is the difference between Flat Seal and other products sold in aerosol cans?


Aerosol products treat tires only after a puncture has occurred. Even then, they offer no more than a temporary seal. The tire will still have to be taken to a repair shop, where it will be broken down, the seal removed, the puncture patched and the tire remounted, all at the customer's expense. (The average cost for this service is $20 or more.) If the flat tire resulted in damage to the rim or sidewalls, the costs will be even higher. In respect to safety hazard, aerosol products are usually highly flammable. Flat Seal is a preventative installed before the fact, and is nonflammable.

  • Is Flat Seal hazardous?


No. Flat Seal is environmentally friendly, non-hazardous, and non-flammable. It even meets the requirements of the California Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65).

  • How does Flat Seal affect the Manufacturer's Warranty?


Flat Seal exceeds the Tire Manufacturer's Warranty by committing to a full reimbursement to the tire user who, after using Flat Seal, experiences a puncture. Flat Seal will not affect the Tire Manufacturer's Warranty.

  • What is the effect of Flat Seal on the tires?


Flat Seal extends the life of the tire. Being a Glycol based product, it protects the tire from excessive heat, prevents porosity, dry rot, and bead and rim leaks.

  • Does Flat Seal extend the life of the tire? In what way and why? How does it perform?


After application, Flat Seal remains liquid for the life of the tire and rim installation. As the tire rotates, centrifugal force spreads the solution evenly over the tread area of the tire. When any puncture occurs, thousands of interlocking fibers seal the opening and prevent any loss of air. This process is repeated each time a puncture occurs.

  • How do you install Flat Seal and how long does it take?


Flat Seal tire life extender is installed quickly and easily through the valve stem (average installation time is just minutes per tire). We have detailed instructions on how to install Flat Seal from 5 gallon pails and retail kits.

  • Can Flat Seal be used only in new or also in used tires?


Both. However if the tires are used, you should add approximately one more ounce of Flat Seal than the chart indicates. Due to open pores of the used tire, some of the Flat Seal will be absorbed into the tire.

  • How many different sizes and containers are used for the marketing of Flat Seal?


Flat Seal comes in 8 Oz Containers and 5 Gallon Containers.

  • Is Flat Seal a registered trademark?


Flat Seal is a registered trademark, registered to Ecopro. FL

  • How many punctures will a measured dose seal?


This cannot be pre-determined as size of opening, air pressure, tire surface area and where the puncture occurs in relation to rotation will vary the results.
