[ Flat Free Questions & Answers ]

[ Flat Free Home Page ] What is FLAT FREE?

    Flat Free 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 underinflation.

How does FLAT FREE seal a hole in the tread of the tire?

    Flat Free 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.

How does FLAT FREE 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.

What is the shelf life of FLAT FREE?

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

Does FLAT FREE react chemically with the rubber tire?

    Not at all. Flat Free is chemically inert.

Is FLAT FREE affected by extreme temperatures?

    Flat Free has been tested to -35o F. (maximum testing ability of laboratory) and has not frozen. This is 67o below the freezing point of water. Furthermore, the tire sealant remains in a stable condition in heat so extreme, the tire itself will disintegrate.

Will FLAT FREE rust the rim of the tire?

    Not at all. Flat Free 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 FREE run to the bottom of the tire when the tire is not in motion?

    No! Flat Free 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 FREE 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 FREE 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 FREE dry out in the tire?

    No! Flat Free 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 FREE?

    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 FREE be used in heavy-duty equipment?

    Yes. Flat Free 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.

Is FLAT FREE covered by product liability insurance?

    Yes, we have $3,000,000 product liability insurance.

What tools do I need to install FLAT FREE?

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

What is the difference between FLAT FREE 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 Free is Glycol based and will not break down or dry up inside the tire. Flat Free, if properly installed, will not affect tire balance.

What is the difference between FLAT FREE 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 Free is a preventative installed before the fact, and is nonflammable.

Is FLAT FREE hazardous?

How does FLAT FREE affect the Manufacturer's Warranty?

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

What is the effect of FLAT FREE on the tires?

    Flat Free 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 FREE extend the life of the tire? In what way and why? How does it perform?

    After application, Flat Free 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 FREE and how long does it take?

    Flat Free 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 Free from 5 gallon pails and retail kits.

Can FLAT FREE 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 Free than the chart indicates. Due to open pores of the used tire, some of the Flat Free will be absorbed into the tire.

How many different sizes and containers are used for the marketing of FLAT FREE?

    Flat Free comes in 8oz. Bottles, Retail Kits of 4 8-ounce Bottles, 16oz. Bottles, 5 Gallon Containers, and 55 Gallon Containers.

Is FLAT FREE a registered trademark?

    Yes. Flat Free is a registered trademark, registered to American Sealant International, Inc. Winter Haven, Florida.

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.
